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 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
