Question
The tetrahedral voids formed by ccp arrangement of Cl- ions in rock salt structure are
Options
A.Occupied by Na+ ions
B.Occupied by Cl- ions
C.Occupied by either Na+ or CI- ions
D.Vacant
Solution
In rock salt structure, Cl- forms fcc (ccp) lattice & Na+ occupies octahedral voids, So tetrahedral voids are vacant.
