We can use the oxidation states of nickel to determine the fraction of Ni2+ in nickel oxide. The oxidation state of oxygen is -2 and since the compound is neutral, the sum of the oxidation states of nickel and oxygen must be zero.

Let x be the fraction of nickel that exists as Ni2+. Then, we can write:

Ni2+: x
Ni3+: (1-x)

The oxidation state of nickel in NiO is +2, so we can set up an equation:

(+2)x + (+3)(1-x) = 0

Solving for x, we get:

x = 0.6

Therefore, 60% of the nickel in nickel oxide exists as Ni2+.
