The total number of octahedral void (s) per atom present in a cubic close packed structure is :

Options

Correct answer

A. 1

Step-by-step solution

In CCP there are four atoms per unit cell octahedral voids are

$12\left(\text{Edge centres}\right)\dfrac{1}{4} + 1\left(\text{Body centre}\right) = 4O . V .$ [Contribution at edge centre is $\dfrac{1}{4}$ ]

Four octahedral voids are present in a unit cell i.e. four atoms.

Therefore, per atom one octahedral void will be present.
