To be used inside {{Infobox element}}. Produces an line of text with proper links. It can take its parameters from existing infobox parameters (no changes needed in most individual infoboxes).

{{infobox element/group
|group={{{group|}}}
|series={{{series|}}}
|number={{{number|}}}
|predicted={{{predicted|}}}
}}

It uses group number to produce (show) basic text & links. This text is overruled by series (lanthanides, actinides, superactinides): they get their own text (currently: the n/a link). All this can be top-overruled by individual atomic number text (e.g. 1 Hydrogen) for special situations.

Required is either one of the three overruling series names or a group number. In case of an error, the template page (not the element article) is listed in Category:Element templates that need attention for maintenance check. The error is not shown on the article page.

group, nr or series shows in infobox note
