In the closest packing atoms, there are

A

One tetrahedral voids and two octahedral voids per atom

B

Two tetrahedral voids and one octahedral void per atom

C

Two of each tetrahedral and octahedral voids per atom

D

One of the each tetrahedral and octahedral void per atom

Text Solution

Verified by Experts

The correct Answer is:
B
In a closest packing of atoms (e.g., `fcc` or `ccp`), there are `4` atoms at lattice point and `8 TV_(s)//"unit cell"`
or `8/4 = 2TVs//"atom"`
or `(4)/(4) = 1 "OV"//"atoms"`
