Template documentation[view] [edit] [history] [purge]

This template adds an automatically generated short description (chemical elements). If the automatic short description is not optimal, override it by adding {{Short description}} at the top of the article.

This template uses Lua:

This template uses TemplateStyles:

Template:Infobox element/styles.css^[e] (sandbox) ^[e]

Infoboxes for the chemical elements use the meta 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 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 energy
ionization energy 2
ionization energy 3

Main isotopes box

As of 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

Reused Main Isotopes table listed in Category:Infobox element isotopes templates (119).

Theoretical elements handling (E119)

As of 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 ... UnbitriumUnbitrium Redirect: no article, no other content pages.

Creation of pages is governed by MOS:NONEWELEMENTS. 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.

Discovered element, for reference. ^ ^a ^b E119 (Ununennium): Article, Infobox, eponymous category, Isotopes article (but no big "§ List of isotopes" table). No Isobox. ^ ^a ^b ^c ^d E121 (Unbiunium): Article, Infobox, eponymous category. ^ ^a ^b ^c ^d ^e ^f ^g E127 (UnbiseptiumUnbiseptium): R-article only, on systematical name. ^ E185 (Unoctpentium): No article, no redirect. As of 4 Jan 2023^[update], conforms MOS:no new elements (no idle pages created; redirects for element names only)
Uue–Uoq (E119–E184) each have an article page by their systematic name. That is 66 article page. Six of these are content pages (articles), and 58 are a redirect. R: Redirects are non-content pages. Treated as non-existant page. E172 would be the end of period 8 ("noble gas") and E173 would be the beginning of period 9. {{Index by periodic table}} · Category:Hypothetical chemical elements (76)

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.

Articles having engvar set: see Category:WikiProject Elements pages using ENGVAR (12)
