Infoboxes for the chemical elements use the core template {{Infobox element}}.

 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. Not every reader is the Seaborg you are. 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 (do not type the _ underscore):

..._2, ..._3

Numbered values make a list.

..._ref

Most parameters have a _ref brother that allows for the reference. This reference is added right after the unit.

..._comment

Parameters with a _comment suffix are added to the end of a line, with a space added. Comments are reproduced without additions (no brackets, no italics, ...).
