A metal crystallises with a face-centred cubic lattice. The edge of the unit cell is 408 pm. The diameter of the metal atom is

A

288 pm

B

408 pm

C

144 pm

D

204 pm

Text Solution

Verified by Experts

The correct Answer is:
A

For a face-centred cubic (fcc) structure, `r = a/(2sqrt2)`
`a = 408 " pm, " r = 408/(2sqrt2)= 144` pm
Diameter `= 2r= 2 xx144 = 288` pm
