Question

CsCl crystallizes in a cubic cell that has a Cl- at each
corner and Cs at the centre of the unit cell if the radius of of Cs
is 1 69Å and rcl - = 1 81Å, what
is the edge length of unit cell?

For BCC ionic crystal (r+ + r-) = root 3 a /2
or a= 2(r+ + r-)/ root 3

=2(1 69+1 81)/root 3 = 4 04 Å

CsCl crystallizes in a cubic cell that has a Cl- at each corner and Cs at the centre of the unit cell.if the radius of of Cs is 1.69Å and rcl - = 1.81Å, what is the edge length of unit cell?
