InterviewSolution

1.	A compound formed by elements X and Y crystallizes in cubic arrangement in which X atoms are at the corners of a cube and Y atoms are at the face centres. What is the formula of the compound ?
Answer» SOLUTION :In one unit cell: `"No. of ATOMS of X" = 8 xx (1)/(8)=1` `"No. of atoms of Y" = 6 xx (1)/(2)=3` `"Formula of compound" =X_(1) Y_(3) = XY_(3)`
