Question

What is the most likely reason that nonmetals are electrical insulators?

Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in
order to fill their valence shells.
O Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their
valence shells,
O Since all nonmetals have valence shells that are full, they hold electrons tightly to avoid changing.
Since all nonmetals have valence shells that are completely empty, they do not attract or release any electrons.

Answer 1

Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.

Step-by-step explanation:

Answer 2

Answer: Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.

Step-by-step explanation:

Electric current can flow freely in a conductor but in an insulator, it cannot flow freely.

The most likely reason that nonmetals are electrical insulators is since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
