In a lattice of X and Y atoms, If X atoms are present at corners and Y atoms at the body centre & one X atom is removed from a corner from each unit cell, then the formula of the compound will be:

A

`X_(7)Y`

B

`X_(8)Y_(7)`

C

`X_(7)Y_(8)`

D

`X_(7)Y_(7)`

Text Solution

Verified by Experts

The correct Answer is:
C
At corner `= (1)/(8)` (for per atom)
`rArr X_(1 - (1)/(8)) Y` (one X atom removed)
`rArr X_(7//8)y`
`rArr x_(7)y_(8)`
