References These references will appear in the article, but this list appears only on this page.
Infoboxes for the chemical element s use the core template {{Infobox element }}.
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>)
Parameter naming patterns
Most parameters have a ... ref that allows for references. This reference is added right after the unit.
ionization energy refParameters 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 commentNumbered values make a list:

{{Periodic table (32 columns, micro) }}
When atomic number ≥ 119, the miniature periodic table shows an extended version (period 8 and up). See, for example, {{Infobox ununennium }}. References These references will appear in the article, but this list appears only on this page.
