STATEMENT -1 : In NaCl structure , Na^(+) ion occupy octahedral holes and Cl^(-) ions occupy ccp. STATEMENT -2 : The distance of the nearest neighours in NaCl structure is a//2 where a is the edge length of the cube .
Statement-1:For NaCl structure, Cl^- ions occupy corners and face centre and Na^+ ions occupy edge centres and body centre. Statement-2:The radius ratio of NaCl structure varies from 0.414 to 0.732
In Zinc blende , the percentage of tetrahedral voids occupied by Zn^(2+) ions is :
In the fluorite structure the coordination number of Ca^(2+) ion is
In Zinc blende structure, Zn^(+2) ions are present in alternate tetrahedral voids and S^(-2) in ccp. The coordination number of Zn^(+2) and S^(-2) are respectively
In the zinc blende structure, zinc ions occupy alternate tetrahedral voids and S^(2-) ions exist as ccp the radii of Zn^(2+) and S^(2-) ions are 0.83Å and 1.74 Å respectively.The edge length of the ZnS unit cell is :
