NEET Chemistry The Solid State Questions Solved

The mass of a unit cell of CsCl corresponds to:-

(a)8Cs+ and Cl-

(b)1Cs+ and 6Cl-

(c)1Cs+ and 1Cl-

(d)4Cs+ and Cl-

(c) A unit cell of CsCl having bcc structure consists of 8 atoms at the corner and one atom at centre.

Thus, no. of Cl- = 8x1/8 =1 and no. of Cs+ =1x1=1

Thus, no. of CsCl unit per unit cell = 1
