Usage
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 format
|group={{{group|}}}<!-- in infobox: symbol-to-group-->
|symbol={{symbol|}}}
|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.
