Template documentation[view] [edit] [history] [purge]

The master template is {{Infobox element isotopes}} (talk).

ParametersEdit

|name=
|symbol=
|isotopes=<!-- tablerow subtemplates, see below -->
|isotopes table footnote=
|conventional atomic weight=
|standard atomic weight=
|standard atomic weight ref=

The 'isotopes' parameterEdit

Isotopes are to be entered by the editor in |isotopes=, using one subtemplate for each isotope. The subtemplate produces one row in the table (possibly with multiple decay mode routes). The infobox adds the outer table form.

Simple demo tablerowsEdit

What |isotopes= input should look like:

Main isotopes of <element> ()
Iso­tope Decay
abun­dance half-life (t1/2) mode pro­duct
19F 100% stable
251Cf trace 898 y α 247Cm

  | mn=19
  | sym=F
  | link=fluorine-19
  | na=100%
}}<!-- a table datarow for one isotope -->
{{Infobox element isotopes/isotopes decay
  | mn=251

  | na=trace
  | hl=898 y
  | dm=α
  | de=6.172
  | pn=247

}}<!-- another table row for another isotope -->
