Parameters
[baguhin ang wikitext]- 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 sets 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 energyionization energy 2ionization energy 3

Main isotopes box
[baguhin ang wikitext]Magmula noong 7 Jan 2023[update], the "Main isotopes of <element>" tabular list will be read directly from the Isobox: "Infobox <element> isotopes". For example, {{Infobox uranium}} will read the table live from {{Infobox uranium isotopes}}.
The headerbar provides View-Edit links to that Isobox.
- Main isotopes of uranium

Theoretical elements handling (E119)
[baguhin ang wikitext]Magmula noong 1 Jan 2023[update], elements E119 and higher are not discovered. These are called theoretical elements. They can have article and other content pages though. Incidentally, this concerns period 8 completely. For the Infobox <element>, their redirected pages do not count (are treated as: "R page does not exist").
Possible situations regarding articles & discovery, are:
- "E118": E1–E118, discovered, existing full set, mentioned here for easy reference
- "E119": E119, E120
- "E121": E121, E122, E124, E126
- "E127, E185": E123, E125, E127 ... Unbitrium Redirect: no article, no other content pages.
Creation of pages is governed by . This infobox must distinguish between three typical (exemplary) elements: E118 (regular element), E119 and E121.
Handling of these element infoboxes is hardcoded in the meta-infobox, set by |number= (Z).
- Theoretical element: above-header shows
- Theoretical element
- Applied: when element is theoretical (E119 and higher).
- No article "Isotopes of <element>": Header does not link
- E119: Main isotopes of ununennium
- E121: Main isotopes of unbiunium
- Applied: E119, E120 do link, E121 and higher do not link.
- No isotopes known, Isobox does not exist: local input, per Infobox. For example:
- Transclusion of the isobox is suppressed (no redlink),
- E119:
|theoretical isotopes comment=Experiments and theoretical calculations
- Applied: E119 and up: have no Isobox, so no isotopes lists is shown—at all. Instead, the parametertext is shown as present.

Subtemplates
[baguhin ang wikitext]These subtemplates are used automatically; they do not need specific editor's input.
- {{Infobox element/pronunciation}} (data)
- {{Infobox element/standard atomic weight format}}
- {{Infobox element/block format}}
- {{Infobox element/periodic table}} (extends period 8 when atomic number ≥ 119. See {{Infobox ununennium}}).
English variant spellings (ENGVAR)
[baguhin ang wikitext]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.
