Point out the correct statement for the set of characteristics of ZnS crystal.

Options

A. Coordination number (4:4) : ccp , `Zn^(2+)` ions in the alternate tetrahedral voids
B. Coordination number (6:6) , hcp, `Zn^(2+)` ions in all tetrahedral voids
C. Coordination number (6:4) , hcp, `Zn^(2+)` ions in all octahedral voids
D. Coordination number (4:4) , ccp, `Zn^(2+)` ions in all tetrahedral voids

Answer

D

Explanation

ZnS has coordination number 4 : 4 having ccp structure where `Zn^(2+)` ions occupy half of the tetrahedral voids .
