Infoboxes for the chemical elements use the core template {{Infobox element}} (talk).

Parameters

In general

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 °C)". For this, you may want to experiment with parameter input too - or propose improvements.

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 <br>)

Central data values

Some data, like standard atomic weight, are read from a central list. This way, enwiki has the same values everywhere. See #Chemical element data lists for more.

Parameter naming patterns

Most parameters have a ... ref that allows for references. This reference is added right after the unit.

ionization energy ref

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

ionization energy comment

Numbered values make a list:

ionization energy
ionization energy 2
ionization energy 3

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.

parameter en-US
(default) 		en-GB en-OED
color color coloUr coloUr
heat vaporization vaporiZation vaporiSation vaporiZation
vapor pressure vapor vapoUr vapoUr
ionization energy ioniZation ioniSation ioniZation
crystal structure (list) -centEred -centred -centred
... oxidation-state/comment parenthesized brackets brackets

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.

Articles having engvar set: see Category:WikiProject Elements pages using ENGVAR (0)
