Question

In a compound, atoms of element y from ccp lattice and those of element x occupy 2/3 of tetrahedral voids. The formula of the compound will be

Answer 1

y= 4

x = 2/3 × 2× 4

= 16/3

Hence its y4x6/3

= y12x16

= y3x4.

Answer 2

• ❤.. The number of tetrahedral voids formed is equal to twice the number of atoms of element B and only 2/3rd of these are occupied by the atoms of element A.
• ❤..Hence the ratio of the number of atoms of A and B is ${2×(2/3):1 or 4:3}$ and the formula of the compound is ${A4B3}$.
