Determine the ionic characteristics of this element. Oxygen


Electrons Can Donate 0, 1, 2, -1, -2, or +2

Electrons Can Receive 0, 1, 2, -1, -2, or +2

Valence (incl. + or -) 0, 1, 2, -1, -2, or +2

Answer 1

Electrons Can Donate - 0

Electrons Can Receive- 2

Valence - 2

Step-by-step 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
