Question

find the oxidation number of Oxygen in Zno​

Answer 1

Answer:

-2

Explanation:

it's simple Zn mostly forms +2 state compounds as Zn = 3d10 4s2, so can lose 2 electrons easily and hence shows +2

Net charge on compound is zero

Charge on Zn*no. of Zn atoms + Charge on O*no. of O atoms = Total charge on compound

Assume oxidation number (charge) on O to be x

2*1 + x*1 = 0

x = -2

Hence, -2 OXIDATION NUMBER of O in ZnO
