The radius of an atom of an element is 5...

The radius of an atom of an element is `500` pm. If it crystallizes as a face-centred cubic lattice, what is the length of the side of the unit cell?

A

176.8 pm

B

1154.7 pm

C

1414 pm

D

1000 pm

Text Solution

Verified by Experts

The correct Answer is:
C
`sqrt2 a=4r`
`a=(4r)/(1.41)`
`=(4xx500)/(1.41)`
= 1414 pm
