Question

In a unit cell containing X2+, Y3+ and Z2- where X2+
occupies 1/8th of tetrahedral voids, y3+ occupies
1/2 of octahedral voids and 22- forms ccp structure.
Then formula of compound is​

Answer 1

Answer:

XY2Z2

Explanation:

atq: z has ccp structure so z has 4 atoms.

therfore charge on z = 2-×4=-8

x has 1/8th tetra hedral voids which means 1 atoms

y has 1/2 octahedral voids which means 1 atom

to balance the charge of -8 we must take 2 atoms of y so that +3×2=6 with x charge ie +2 it will balance.
