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

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.
