NEET Chemistry The Solid State Questions Solved


In a metal oxide, the oxide ions are arranged in hexagonal close packing and metal ions occupy two third of the octahedral voids. The formula of the oxide is

1. MO

2. M2O3

3. MO2

4. M2O

(2) Suppose the number of oxide ions = N

The number of octahedral voids = N

Metal ions in octahedral voids = 2/3 N

Therefore, the ratio of M:O2 = 2/3:1 or 2:3 or the formula is  M2O3
