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

A

`MO`

B

`M_(2)O_(3)`

C

`MO_(2)`

D

`M_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
b
Suppose the number of oxide into` = N`
The number of osctatabedral voids `= N`
Metal ions in ocytabral void `= 2//3N`
Therefore the ratio of `M: O^(2) = 2//3 : 1 or 2: 3 `of the formula is `M_(1)O_(1)`
