Question

Consider an atom (B) lying in the square planar void created by atoms of A. The radius of B is $r_B.$ In another lattice, atom (C) lies in the octahedral void created by atoms of A and the radius of atom $C$ is $r_C.$ Assuming both these crystals to be ideal, the correct statement is

• A. $r_B=2r_c$
• B. $r_e=r_c$
• C. Information insufficient
• D. $r_B<r_c$

Answer 1

The correct option is B $r_e=r_c$

In octahedral void, there is a square planar void.
