Sodium chloride , NaCl , usually crystallizes in a face - centered cubic lattice. How many ions are in contact with any single `Na^(+)` ion ?

A

4

B

6

C

8

D

1

Text Solution

Verified by Experts

The correct Answer is:
B
In NaCl having fcc structure, each `Na^(+)`ion is surrounded by six `Cl^(-)`ion at the corners of a regular octahedron.
