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 Edge centres 1 4 + 1 Body centre = 4   O . V . [Contribution at edge centre is 1 4 ] Four octahedral voids are present in a unit cell i.e. four atoms. Therefore, per atom one octahedral void will be present.
