Question

What is the valency of sodium oxide ?

Answer for points

Answer 1

Explanation:

1 is the valancy of sodium oxide .

Sodium oxide is an ionic compound made up of sodium ions and oxide ions. As we know that the electronic configuration of Na is 2,8,1. Since only one electron is present in the outermost shell or valence shell. Hence, its valency is +1.
