Question

Determine the ionic characteristics of this element, oxygen. Electrons that it can donate and Receive and there valence.

Answer 1

Oxygen is an element in the sixth group of the periodic table. This means it contains 6 electrons in its valence shell. Therefore, to complete its octet, it will prefer to gain two electrons rather than to donate 6. This is why its valency is -2. The relatively easy to achieve octet makes Oxygen a reactive element. 

Answer 2

Oxygen:

electrons can donate: 0

Electrons can receive: 2

Valence: -2

I got a 100% on this question in my lesson. Hope this helps!
