Answer 1

Answer:

Electrons Can Donate - 0

Electrons Can Receive- 2

Valence  - 2

Explanation:

The electronic configuration of oxygen is $1s^2s^22p^4$. Thus in the p-orbital there is deficiency of two electrons. Hence, it can receive/share electron but it cannot donate electrons. This makes oxygen as a good electron acceptor. Since there is a deficiency of two electrons in the outermost shell of oxygen, the valence of oxygen in thus -2
