A solid is made up of two elements P and Q. P atoms are in ccp arrange – InterviewSolution

1.	A solid is made up of two elements P and Q. P atoms are in ccp arrangement while atoms Q occupy all the octahedral voids and half of thetetrahedral voids. The formula of the compound is :
Answer» `PQ_(2)` PQ `PQ_(3)` `P_(2)Q` SOLUTION :For each Q atom, there will be two tetrahedral sites. Since only half tetrahedral sites are occupies, number of P atoms will be same as number of Q atoms . Formula `:` PQ
