|isotopes table footnote=

The 'isotopes' parameter

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.

• {{Infobox element isotopes/isotopes stable}}
• {{Infobox element isotopes/isotopes decay}}
• {{Infobox element isotopes/isotopes decay2}}
• {{Infobox element isotopes/isotopes decay3}}
• {{Infobox element isotopes/isotopes decay4}}
• |isotopes table footnote=

• {{Infobox element isotopes/infotable}} -- the outer table and columnheaders, added by the infobox.

Simple demo tablerows
