Which feature is not typically associated with nonmetals?

Nonmetals are characterized by several distinct features that set them apart from metals. One prominent characteristic is their poor conductivity of electricity. Nonmetals typically have high ionization energies and electronegativities, which means they do not easily lose electrons to create a flow of electric current, unlike metals that are good conductors due to their free-moving electrons. Therefore, lack of conductivity is a significant reason why high conductivity is not a feature associated with nonmetals.

In contrast, nonmetals can form covalent oxides (which involves sharing electrons rather than transferring them as in ionic bonds), exhibit lower melting points compared to metals (many nonmetals are gases or low-melting solids at room temperature), and can indeed form negative ions (anions) by gaining electrons during chemical reactions, reflecting their tendency to gain rather than lose electrons. Thus, identifying high conductivity as a feature that is not commonly linked to nonmetals highlights the fundamental differences between these elements and metals.
