Template:Infobox element/doc

Infoboxes for the chemical elements use the core template Infobox element.

Parameters
Usually parameters reproduce the value, and the template adds the SI unit or additional standard text. While the topic is technical, we can strive to make the result readable text, and even verbose. For example, this is why the template writes "(at 0 &deg;C)". For this, you may want to experiment with parameter input too - or propose improvements.
 * In general

All this can vary across the values (data rows). So depending on the row and the specific value, additional formattings may be added by the template (e.g., a newline ) Some data, like standard atomic weight, are read from a central list. This way, enwiki has the same values everywhere. See for more. Most parameters have a  that allows for references. This reference is added right after the unit.
 * Central data values
 * Parameter naming patterns:

Parameters with a  suffix are added to the end of a data line, with a space added. Comments are reproduced without formatting additions (no brackets, no italics, ...):

Numbered values make a list:

Chemical element data sets
Infobox element reads data from these lists (i.e., not by parameter)

Isotopes

 * none suppresses the table (-header). See E122, E124.
 * E119 and higher do not have a page . Their infoboxes do not have a link then.

Isotopes are to be entered by the editor usingin these subtemplates:

Examples (from various elements):
 * isotopes =

|isotopes comment=reference * = excited state produces the subtable:

Other
Other subtemplates are used automatically; they do not need specific editor's input.
 * Infobox element/pronunciation (data)
 * Infobox element/standard atomic weight format
 * Infobox element/group format
 * Infobox element/block format
 * Infobox element/period format
 * Infobox element/periodic table (extends period 8 when atomic number ≥ 119. See Infobox ununennium).
 * Bare Periodic table, micro


 * Infobox element/spectral lines
 * Infobox element/vapor pressure table
 * Infobox element/crystal structure

English variant spellings (ENGVAR)
All element articles and their infoboxes use IUPAC spelling of elements and compounds. Notably, that is aluminium, sulfur, caesium, not aluminum, sulphur, cesium. For other English variant words (vapor vs. vapour) the infobox reads engvar. The parameter should be set in the article, and has options: en-US (or blank; default), en-GB, en-OED. Note, what is shown in the infobox is not influenced by the parameter name spelling, nor its input value.

See this demo for actual engvar effects.
