What is the formula of a compound in which the element Y forms ccp lattice and atoms X occupy 1/3rd of tetrahedral voids ?

Text Solution

Verified by Experts

The correct Answer is:
`Al_(2)O_(3)`
Suppose no. of atoms Y present in the packing = n
Atoms X present in the tetrahedral voids =` 1/3 xx 2n = (2n)/3`
Ratio of X :Y =` ( 2n)/ 3 : n = 2/3 :1 = 2: 3`
Hence, the formula is ` X_(2) Y_(3)` .
