^The thermal expansion of cobalt is anisotropic: the coefficients for each crystal axis are (at 20 °C): αa = 10.9×10−6/K, αc = 17.9×10−6/K, and αaverage = αV/3 = 12.9×10−6/K.

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

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, ...):

As of 7 Jan 2023, 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.
As of 1 Jan 2023, 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
"E127, E185": E123, E125, E127 ...Unbitrium 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
As of 4 Jan 2023, 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.
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.
