Oxidation number of silicon

Step 1 :

Given: The Compound is CaO. The Oxidation state of Calcium Ca = 2 and for Oxygen O = -2.

Step 2 :

Over all oxidation state for the compound would be (+2 ) x 1 + (-2) x 1 = 2 – 2 = 0

Answer :

Hence the Oxidation state of Calcium is +2 and Oxygen is -2 and the compound is said to be stable.
