A solid is made of two element P and Q. Atoms P are in ccp arrangement

1.	A solid is made of two element P and Q. Atoms P are in ccp arrangement and atoms Q occupy all the octahedral voids and half of the tetrahedral voids, then the simplest formula of the compound is(a) PQ2 (b) P2Q (c) PQ (d) P2O2
Answer» Correct Option (a) PQ₂ Explanation : Four atoms P contributes to one unit cell from ccp arrangement and 4 atoms Q from the all octahedral voids and 4 atoms Q from the half of the tetrahedral void contributes one unit cell. So, formula of solid is P₄O₈so, the simplest formula of the solid is PQ₂.

Answer»

Correct Option (a) PQ₂

Explanation :

Four atoms P contributes to one unit cell from ccp arrangement and 4 atoms Q from the all octahedral voids and 4 atoms Q from the half of the tetrahedral void contributes one unit cell. So, formula of solid is P₄O₈so, the simplest formula of the solid is PQ₂.
