Chemical elements in East Asian languages

The names for chemical elements in East Asian languages, along with those for some chemical compounds (mostly organic), are among the newest words to enter the local vocabularies. Except for those metals well-known since antiquity, most elements had their names created after modern chemistry was introduced to East Asia in the 18th and 19th century, with more translations being coined for those elements discovered later.

While most East Asian languages use—or have used—the Chinese script, only the Chinese language uses the characters as the predominant way of naming elements. On the other hand, the Japanese, Koreans and Vietnamese primarily employ native writing systems for the names of the elements, such as Katakana, Hangul and Quốc Ngữ, respectively.



In Chinese, characters for the elements are the last officially created and recognized characters in the Chinese writing system. Unlike characters for unofficial varieties of Chinese (e.g., written Cantonese) or other now-defunct ad hoc characters (e.g., those by the Empress Wu), the names for the elements are official, consistent, and taught (with Mandarin pronunciation) to every Chinese and Taiwanese student who has attended public schools (usually by the first year of middle school). New names and symbols are decided upon by the China National Committee for Terms in Sciences and Technologies.[1]

Native charactersEdit

Some metallic elements were already familiar to the Chinese, as their ores were already excavated and used extensively in China for construction, alchemy, and medicine. These include the long-established group of "Five Metals" (五金) — gold (金), silver (銀/银), copper (銅/铜), iron (鐵/铁), and tin (錫/锡) — as well as lead (鉛/铅) and mercury (汞).

Some non-metals were already named in Chinese as well, because their minerals were in widespread use. For example,

Characters based on European pronunciationsEdit

However, the Chinese did not know about most of the elements until they were isolated during the Industrial Age. These new elements therefore required new characters, which were invented using the phono-semantic principle. Each character consists of two parts, one to signify the meaning and the other to hint at the sound:

  1. The semantic (meaning) part is also the radical of the character. It refers to the element's usual state at room temperature and standard pressure. There are only four radicals used for elements: / (jīn "gold; metal") for solid metals, (shí "stone, rock") for solid non-metals, / (shuǐ "water") for liquids, and ( "air, steam") for gases.
  2. The phonetic (sound) part represents the character's pronunciation and is a partial transliteration of the element. For each element character, this is a unique phonetic component. Since 118 elements have been discovered, there are over 100 different phonetic components used in naming the elements. Current practice dictates that new names should avoid being homophonous with previous element names, or with organic functional groups. However, this rule was not rigorously followed in the past, and confusingly, tin (锡) and selenium (硒) have names that are both pronounced xī.[2] To avoid further confusion, P.R.C. authorities avoided using the name 矽 for silicon.
Examples of characters derived from European pronunciations
Semantic Phonetic Element Source
/ + = / () lithium
/ + jiǎ = / (jiǎ) kalium, Latin name for potassium
/ + / nèi or = / () natrium, Latin name for sodium
/ + or = / (tì/tī) stibium, Latin name for antimony
/ + niè = / (niè) nickel
/ + = / () cadmium
/ + / = / () wolframium, Latin name for tungsten
/ + = / () bismuth
/ + yóu = /

/ + / = / () aluminium
+ diǎn = (diǎn) iodine
+ hài = (hài) helium
+ = () fluorine
+ nǎi = (nǎi) neon
+ guī = (guī) silicon (P.R.C.), from Japanese transliteration

'珪' (kei, けい) of archaic Dutch 'keiaarde'.

Note that R.O.C. (Taiwan), Hong Kong,

and Macau use 矽 derived from silicon.

/ is primarily pronounced as nèi, but has less commonly as , the source of /. Likewise, the primary pronunciation of is , but the alternate reading of gave rise to .
* The derived pronunciation differs (in tone or in sound) from the pronunciation of the element.

The "water" radical () is rarely used, since only two elements (bromine and mercury) are truly liquid at standard room temperature and pressure. Both of their characters are not based on the European pronunciation of the elements' names. Bromine (), the only liquid nonmetal at room temperature, is explained in the following section. Mercury (), now grouped with the heavy metals, was long classified as a kind of fluid in ancient China.

Meaning-based charactersEdit

A few characters, though, are not created using the above "phono-semantic" design, but are "semantic-semantic", that is, both of its parts indicate meanings. One part refers to the element's usual state (like the semanto-phonetic characters), while the other part indicates some additional property or function of the element. In addition, the second part also indicates the pronunciation of the element. Such elements are:

Semantic Semantic Element English Note
/ + bái (white) = / [note 1] platinum The character is repurposed.[note 2]
+ chòu (stinky) = xiù[note 1] bromine odorous (Greek βρῶμος brómos also means "stench")
+ yáng, short for / yǎng (to nourish/foster) = yǎng[note 3] oxygen A continuous supply of oxygenated air nourishes almost all animals
+ /𢀖 jīng, short for / qīng (light-weight) = / qīng[note 3] hydrogen the lightest of all elements
+ / , short for /绿 (green) = / [note 3] chlorine greenish yellow in color
+ yán, short for dàn (diluted) = dàn[note 3] nitrogen dilutes breathable air
+ lín, short for lín (glow) = lín phosphorus emits a faint glow in the dark
  1. ^ a b The pronunciation of these characters come from the second semantic characters' nearly obsolete pronunciations. Nowadays 白 (white) is normally pronounced bái in the standard Mandarin dialect, although traditionally bó was preferred. Similarly, (stinky) is almost always pronounced chòu, as opposed to x, now an archaic reading.
  2. ^ The original meaning of / is "thin sheet of gold" (now obsolete). The character was not associated with platinum until modern time, since platinum was known in the Old World only after the Age of Discovery.
  3. ^ a b c d The apparent mismatch in pronunciation with the phonetic component is because the pronunciation is inherited from another character that provides the meaning. For example, the ultimate source of the pronunciation of yǎng (oxygen) is not yáng (sheep), but / yǎng (to nourish/foster).

Recently discovered elementsEdit

In 2015, IUPAC recognised the discovery of four new elements. In November 2016, IUPAC published their formal names and symbols: nihonium (113Nh), moscovium (115Mc), tennessine (117Ts), and oganesson (118Og).

Subsequently, in January 2017, the China National Committee for Terms in Sciences and Technologies published four naming characters for these elements.[1] The National Academy for Educational Research under the Ministry of Education of the Republic of China on Taiwan published an identical list in April 2017.[3] For traditional Chinese, nihonium and moscovium were then existing characters; while in simplified Chinese, only moscovium already existed in the Unicode Standard. The missing characters were added to Unicode version 11.0 as urgently-needed characters in June 2018.[4]

The Chinese characters for these symbols are:

Nihonium: Traditional: U+9268 (HTML 鉨) Simplfied: U+9FED (HTML 鿭)   ()
Moscovium: Traditional: U+93CC (HTML 鏌) Simplfied: U+9546 (HTML 镆) ()
Tennessine: Both Traditional and Simplfied: U+9FEC (HTML 鿬)   (tián)
Oganesson: Both Traditional and Simplfied: U+9FEB (HTML 鿫)   (ào)

In the periodic tableEdit

americium 95 méi méi mei4, mui4
berkelium 97 péi běi pui4, bak1
californium 98 kāi hoi1, kaa1
einsteinium 99 āi ài oi1, oi3

A minority of the "new characters" are not completely new inventions, as they coincide with archaic characters, whose original meanings have long been lost to most people. For example, (protactinium), (beryllium), (chromium), and (lanthanum) are obscure characters meaning "raw iron", "needle", "hook", and "harrow" respectively.

The majority of the elements' names are the same in Simplified Chinese and Traditional Chinese, merely being variants of each other, since most of the names were translated by a single body of standardization before the PRC-ROC split. However, since francium and the transuranium elements were discovered during or after the split, they have different names in Taiwan and in Mainland China. In Hong Kong, both Taiwanese and Mainland Chinese names are used.[5]

The isotopes of hydrogen – protium (1H), deuterium (D) and tritium (T) – are written 氕 piē, 氘 dāo and 氚 chuān, respectively, in both simplified and traditional writing. 鑀 is used in Taiwan for both einsteinium (mainland China: 锿) and ionium, a previous name for the isotope thorium-230.[citation needed]


Like other words in the language, elements' names in Japanese can be native, from China (Sino-Japanese) or from Europe (gairaigo).

Names based on European pronunciationsEdit

Even though the Japanese language also uses Chinese characters (kanji), it primarily employs katakana to transliterate names of the elements from European languages (often German/Dutch or Latin [via German] or English). For example,

English Japanese Note
antimony anchimon (アンチモン) This form without the final vowel (i from y) is likely from Dutch (antimoon) or German (Antimon)
tungsten tangusuten (タングステン) from English; other major European languages refer to this element as wolfram or tungsten with some additional syllable (-o, -e, etc.).
sodium natoriumu (ナトリウム) natrium in Latin
uranium uran (ウラン) Uran in German
iodine yōso (ヨウ素 / 沃素) -yō (ヨウ, "io-" [joː], like German Jod [joːt]) + -so (, "element/component"). Chinese uses (diǎn), the second syllable of iodine.
fluorine fusso (弗素) futsu () approximates flu-. Similar to the Chinese: , plus the "air" radical (气). As is not a commonly used kanji, it is often written フッ素, using katakana.

Native namesEdit

On the other hand, elements known since antiquity are Chinese loanwords, which are mostly identical to their Chinese counterparts, albeit in the Shinjitai, for example, iron () is tetsu (Tang-dynasty loan) and lead () is namari (native reading). While all elements in Chinese are single-character in the official system, some Japanese elements have two characters. Often this parallels colloquial or everyday names for such elements in Chinese, such as 水銀/水银 (pinyin: shuǐyín) for mercury and 硫黃/硫黄 (pinyin: liúhuáng) for sulfur. A special case is tin (, suzu), which is more often written in katakana (スズ).

English Japanese Chinese Note
mercury suigin (水銀) (gǒng) lit. "watery silver" aka. quicksilver, like the element's symbol, Hg (Latin/Greek hydro-argyrum, "water-silver"). In the Greater China Region, 水銀/水银 is being used wider than 汞 because 汞 usually won't be taught until the chemistry class but 水銀/水银 is the word used in daily life; for example, when people talk about the mercury liquid in the thermometer, most people would say "水銀/水银" but not 汞. This kind of thermometer is called "水銀溫度計/水银温度计" (lit. "watery silver thermometer") in Chinese instead of "汞溫度計/汞温度计" (lit. "mercury thermometer"), which is not being used at all. However, is also exists in Japanese, but extremely rare, serves as an alternative reading of the obsolete reading mizugane.
sulfur , formerly iwō (硫黄) (liú) (ō) means "yellow", to distinguish from other characters pronounced the same.
zinc aen (亜鉛) 鋅/锌 (xīn) meaning "light lead"; 鉛 is "lead" in Japanese and Chinese.
platinum hakkin (白金) (bó) lit. "white gold". Like 水銀/水银 and 汞 in Chinese, 白金 is the "daily" word, and 鉑/铂 is the formal name and usually won't be taught until the chemistry class. In mainland China, jewelry stores usually use the word "白金" or "铂金".
arsenic hiso (砒素) (shēn) hi () < (砒霜) hishima, the Chinese name for arsenic trioxide (pīshuāng). In modern Chinese, arsenic is instead shēn (砷), an approximation of the second syllable of arsenic.

The kanji is quite rare. Often written ヒ素 using katakana.

boron hōso (硼素, "borax element") (péng) (ホウ) < hōsa (硼砂), the Chinese name for borax (péngshā). Boron is still called péng in modern Chinese.

The kanji is extremely rare. Mostly written ホウ素 using katakana.

Meaning-based namesEdit

Some names were later invented to describe properties or characteristics of the element. They were mostly introduced around the 18th century to Japan, and they sometimes differ drastically from their Chinese counterparts. The following comparison shows that Japanese does not use the radical system for naming elements like Chinese.

English Japanese Chinese Note
hydrogen suiso (水素, "water's element") 氫/氢 (qīng) translation of the hydro- prefix
carbon tanso (炭素, "coal element") (tàn) translation of the German word for carbon, Kohlenstoff ("coal substance").
nitrogen chisso (窒素, "the suffocating element") (dàn) translation of the German word for nitrogen, Stickstoff ("suffocating substance"). While nitrogen is not toxic per se, air-breathing animals cannot survive breathing it alone (without sufficient oxygen mixed in).
oxygen sanso (酸素, "acid's element") (yǎng)

similar to the German word for oxygen, Sauerstoff ("sour substance") or the Greek-based oxygen ("acid maker").
Many 19th-century European chemists erroneously believed that all acids contain oxygen. (Many common ones do, but not all.)

silicon keiso (硅素 / 珪素) (guī) same as Chinese; the kanji is extremely rare. Often written ケイ素 using katakana.
phosphorus rin () (lín) similar to Chinese, except the "stone" radical replacing the "fire" radical. The kanji is rare. Usually written リン using katakana.
chlorine enso (塩素, "salt's element") (lǜ) it and sodium make up common table salt (NaCl); is the Shinjitai version of .
bromine shūso (臭素, "the stinky element") (xiù) similar to Chinese, except the lack of the "water" radical.


As the Hanja (Sino-Korean characters) are now rarely used in Korea, all of the elements are written in Hangul. Since many Korean scientific terms were translated from Japanese sources, the pattern of naming is mostly similar to that of Japanese. Namely, the classical elements are loanwords from China, with new elements from European languages. But recently, some elements' names were changed. For example:

English Korean (before 2014) Source (South) Korean (after 2014)
gold geum (금) from Chinese jin (金) geum (금)
silver eun (은) from Chinese yin (銀) eun (은)
antimony antimon (안티몬) from German antimoni (안티모니)
tungsten teongseuten (텅스텐) from English teongseuten (텅스텐)
sodium nateuryum (나트륨) from Latin or German (Na for natrium) sodyum (소듐)
potassium kalyum (칼륨) from Latin or German kalium potasyum (포타슘)
manganese manggan (망간) from German Mangan mangganijeu (망가니즈)

Pre-modern (18th-century) elements often are the Korean pronunciation of their Japanese equivalents, e.g.,

English Korean (Hangul, hanja)
hydrogen suso (수소, 水素)
carbon tanso (탄소, 炭素)
nitrogen jilso (질소, 窒素)
oxygen sanso (산소, 酸素)
chlorine yeomso (염소, 鹽素)
zinc ayeon (아연, 亞鉛)
mercury sueun (수은, 水銀)


Some of the metals known since antiquity are loanwords from Chinese, such as copper (đồng from ), tin (thiếc from ), mercury (thuỷ ngân from 水銀), sulfur (lưu huỳnh from 硫黄), oxygen (dưỡng khí from 氧氣; ôxy is the more common name) and platinum (bạch kim from 白金; platin is another common name). Others have native or old Sino-Vietnamese names, such as sắt for iron, bạc for silver, chì for lead, vàng for gold, kền for nickel (niken is the more common name) and kẽm for zinc. In either case, now they are written in the Vietnamese alphabet. Before the Latin alphabet was introduced, sắt was rendered as 𨫊, bạc as , chì as 𨨲, vàng as , kền as 𨪝 and kẽm as 𨯘 in Chữ Nôm.

The majority of elements are shortened and localized pronunciations of the European names (usually from French). For example:

  • Phosphorus becomes phốtpho.
  • The -ine suffix is lost, e.g., chlorine, iodine and fluorine become clo, iốt and flo, respectively.
  • The -um suffix is lost, e.g., caesium becomes xêzi, pronounced /sezi/; compare the French césium, pronounced /sezjɔm/ (whereas the English is /sizi-/).
    • Similarly, beryllium, tellurium, lithium, natrium (sodium), and lanthanum become berili, telua, liti, natri, and lantan respectively
  • The -gen suffix is lost, e.g., nitrogen, oxygen and hydrogen become nitơ, ôxy and hiđrô, respectively

A minority of elements, mostly those not suffixed with -ium, retain their full name, e.g.,

  • Tungsten (aka wolfram) becomes volfram.
  • Bismuth becomes bitmut.
  • Aluminium becomes nhôm (), because the ending -nium has a similar pronunciation. It was the first element to be known in English in Vietnam.
  • Elements with the -on suffix (e.g. noble gases) seem to be inconsistent. Boron and silicon are respectively shortened to bo and silic. On the other hand, neon, argon, krypton, xenon and radon do not have common shorter forms.
  • Unlike the other halogens, astatine retains its suffix (astatin in Vietnamese).
  • Antimony is shortened to antimon, and arsenic to asen; these names are similar to the German ones (Antimon and Arsen, respectively).

Some elements have multiple names, for instance, potassium is known as pô-tát and kali (from kalium, the element's Latin name).
