What is Unmetalled?

Unmetalled refers to a situation where a metal or a metalloid does not have any unpaired electrons, i.e., all its valence electrons are paired with other atoms or molecules. In this state, the metal or metalloid is said to be "unmetallized" or "devoid of metallic character".

In contrast, metals typically have one or more unpaired electrons, which are responsible for their conductive and malleable properties. When a metal is placed in a chemical compound or solution, it can donate or accept electrons to form covalent bonds with other atoms or molecules, leading to the formation of a solid or solution.

Unmetalled species, on the other hand, do not have any unpaired electrons and therefore do not exhibit metallic behavior. They may be more similar to nonmetals or metalloids in their properties and behavior.
