Template:NavPeriodicTable/doc

Usage

 * Mostly in.

Extension by atomic number
The template takes parameter number= (think atomic number). When this number is >118, the template expands with group 8 rows, adding the (predicted) elements with atomic number 119–+. Apart from this 118+ switching, the parameter is not used as an atomic number, so to force the expansion one can also write:
 * &rarr;

Marking elements
And element (table cell) is marked by a black border line on its article page (see Carbon). Cells can also be marked by group (column) and by category (chemical property, background color). To do so, use parameter mark and a group number (1-18) or category name (exactly spelled as in NavPeriodicTable/Elementcell or the mouse hover text. See for example Alkaline metal.
 * &rarr;


 * Note: Group=-1 will mark ungrouped elements (actinides, lanthanides, Uus, Uuo). Group=-2 will mark the whole extended range (Z=119 and higher; period 8)
 * Note: "(predicted)" categories are named differently, colored differently, and so cannot be grouped (marked) together with its "discovered" parent category.
