A cubic crystalline solid contains A atoms at the comers and B atoms at the body centres. If one atom from a comer is missing, what will be the simplest formula of the resulting solid?

Text Solution

Verified by Experts

Number of A atoms per unit cell when I atom at one corner is missing = 7(1/8) = 7/8
Number of atoms of B atoms per unit cell = `1xx1=1`
The simplest formula is A(7/8) B(1) = `A_(7)B_(8)`
