Solution

Oxidation number: Oxidation number denotes the oxidation state of an element in a compound ascertained according to a set of rules formulated on the basis that electron pair in a covalent bond belongs entirely to a more electronegative element.

Calculating the oxidation number of Calcium(Ca) in Calcium oxide (CaO):

The oxidation state of Oxygen(O) = -2

Consider the oxidation state of Calcium(Ca) = x

Now,

x-2=0x=+2

Hence, the oxidation number of Calcium in Calcium oxide is +2.
