In a face centred cubic arrangement of A...

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

A

`A_(7)B_(3)`

B

`AB_(3)`

C

`A_(7)B_(24)`

D

`A_(2)B_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`A=7xx(1)/(8)=(7)/(8)," "B=6xx(1)/(2)=3`
Formula `=A_(7//8)B_(3)or A_(7)B_(24)`
