CsCl crystallises in body-centred cubic lattice. If a is its edge length then which of the following expressions is correct?
- \(r_{\mathrm{Cs}^{+}}+r_{\mathrm{Cl}^{-}}=\sqrt{3} a\)
- \(r_{\mathrm{Cs}^{+}}+r_{\mathrm{Cl}^{-}}=3 a\)
- \(r_{\mathrm{Cs}^{+}}+r_{\mathrm{Cl}^{-}}=\frac{3 a}{2}\)
- \(r_{\mathrm{Cs}^{+}}+r_{\mathrm{Cl}^{-}}=\frac{\sqrt{3}}{2} a\)
Answer
(A) r_ Cs ^ + +r_ Cl ^ - = 3 a
