Answer:

+4

Explanation:

In PbO

2

​

, oxygen exhibits an oxidation number of −2 (since it's not a peroxide or superoxide).

Let the oxidation number of Pb be x. Then, for the compound to be neutral, the oxidation numbers of all atoms should add up to zero.

⇒x+(−2)+(−2)=0

     x=+4

So the oxidation no. of Pb is +4.
