Explanation:

Metal and nonmetal bonded together is ionic bonding.

Metallic element Sodium donates its extra valence electron to the complete Oxygen's octet (Oxygen had 6 valence electrons but when Sodium donates its 2 valence electrons, it makes the octet of 8).

The transfer of electrons is known as ionic bonding.
