In a face centered cubic arrangement of A and B atoms whose A atoms are at the corner of the unit cell and B atoms at the face centers. One of the B atoms missing from one of the face in unit cell. The simplest formula of compounding is:

Text Solution

Verified by Experts

The correct Answer is:
`A_(7)B_(24)`
Corners share `= 7 xx (1)/(8) = (7)/(8)`
Face centre share `= 6 xx (1)/(2) = 3`
Formula: `A_(7//8)B_(3)` or `A_(7)B_(24)`.
