Question

A solid is made up of two elements p and q. atoms of q are in ccp arrangement while atoms of p occupies all the tetrahedral sites what is the formula of the compound

Answer 1

P4Q is the molecular formula of the compound.

Answer 2

Hey !!

Suppose number of atoms of Q in CCP arrangement = N

So, therefore number of tetrahedral sites = 2 N

          Number of P atoms = 2 N

                   P : Q = 2N : N = 2 :1

Hence, formula of compound is P₂Q
