Copper crystallises in a face-centred cubic lattice with a unit cell length of 361 pm. What is the radius of copper atom in pm?
Multiple Choice Options
- A 157
- B 181
- C 108
- D 128
Step-by-Step Verified Solution
Since Cu crystallises in a face-centred
cubic lattice,
Atomic radius, r = a 2 2
_ r = 361 2 2 = 128 pm
