Question

Given that interionic distance in Na+ F- crystal is 2.31(Ao) and = 1.36(Ao), which of the following predictions will be right

Options

A.rNa+/rF- ≈ 0.7
B.coordination number of Na+ = coordination nunber of F- = 6
C.Na+ F- will have rock salt type crystal structure
D.effective nuclear charge for Na+ and F- are equal

Solution

Na+ & F- are isoelectronic hence they will have same screening const (s) but not the effective nuclear charge.
