Summary
| Description |
English: Periodic table with elements colored according to the half-life of their most stable isotope. 32-column format is helpful in showing stability pattern.
Elements that contain at least one stable isotope.
Radioactive elements: the most stable isotope is very long-lived, with half-life of over four million years.
Radioactive elements: the most stable isotope has half-life between 800 and 34.000 years.
Radioactive elements: the most stable isotope has half-life between one day and 103 years.
Highly radioactive elements: the most stable isotope has half-life between several minutes and one day.
Extremely radioactive elements: the most stable isotope has half-life less than several minutes. Very little is known about these elements due to their extreme instability and radioactivity. Note that this table only addresses the most stable isotope of each element. Therefore it would be erroneous to conclude that all naturally occurring elements from hydrogen through lead are non-radioactive. For example, if you hold a geiger counter up to a banana, you will detect radioactivity because of the potassium isotope 40K, which is also the most common radioisotope in the human body. |
