Are metals considered electronegative or not? Explain how this affects if metals are conductive or not.
Metals are not very electronegative, so they conduct electricity since they are not very greedy for electrons.
400

Are nonmetals considered electronegative or not? Explain how this affects if nonmetals are conductive or not.

Nonmetals are very electronegative, so they do not conduct electricity since they are quite greedy for electrons.
