Adding references[edit]

References can be added as usual. When using a named reference both on the page and in the infobox, like

<ref name="CRC">{{cite book|...}}</ref>

add the full definition on both pages (best use copy-paste). In the article, they will merge nicely.

Hydrogen example[edit]

Atomic number 119 and above[edit]

When the atomic number is ≥ 119, the miniature periodic table shows an extended version (period 8). See for example {{infobox ununennium}}.

Subtemplates used[edit]

Isotopes[edit]

Isotopes subtemplates are to be entered by the editor:

Example from hydrogen:

| isotopes =
{{Infobox element/isotopes stable| mn=1 | sym=H | na=99.985% | n=0 | link=Hydrogen atom}}
{{Infobox element/isotopes stable| mn=2 | sym=H | na=0.015% | n=1 | link=Deuterium}}
{{Infobox element/isotopes decay | mn=3 | sym=H | na=[[Trace radioisotope|trace]] | hl=12.32 [[years|y]] | dm=[[beta minus decay|β<sup>−</sup>]] | de=0.01861 | link1=helium-3 | pn=3 | ps=He | link=Tritium}}

produces the subtable:

1H 99.985% 1H is stable with 0 neutrons
2H 0.015% 2H is stable with 1 neutron
3H trace 12.32 y β 0.01861 3He
