Q5 of 22 Page 1

What is the formula of a compound in which the element Y forms ccp lattice and atoms of X occupy 2/3 rd of tetrahedral voids?

Since, Y forms ccp lattice, the no. of atoms of Y =


= 4


No. of tetrahedral voids in lattice = 2 (no. of atoms of Y)


= 2


Since, X occupy 2/3rd of tetrahedral voids, then no. of atoms of Y = 8 =


Formula of compound =


= X4Y3
