If the distance between `Na^(+)` and `Cl^(-)` ions in NaCl crystals is 265 pm, then edge length of the unit cell will be ?

A

265 pm

B

795 pm

C

132.5 pm

D

530 pm

Text Solution

Verified by Experts

The correct Answer is:
D
In NaCl crystal , Edge length = 2 x distance between `Na^+` and `Cl^-`
=2 x 265 = 530 pm
