Which of the following statement(s) is (are) correct? — Solid State Chemistry Question

💡 Solution & Explanation

CsCl has an 8:8 coordination number. A BCC metal has a coordination number of 8, not 12. Ions located at corners, edges, and faces are shared among adjacent unit cells. In NaCl, the edge length is $a = 2(r_{Na^+} + r_{Cl^-}) = 2(95 + 181) = 552$ pm. Therefore, correct answer is A,C,D.
