Question
Silver (atomic mass = 108) has an atomic radius of 144 pm and density 10.6 g/ cm3. To which type of cubic crystal silver belongs?
Options
A.Simple
B.BCC
C.FCC
D.End-centred
Solution
Packing fraction = $\frac{\left( 6 \times 10^{23} \right) \times \frac{4}{3}\pi \times \left( 144 \times 10^{- 10} \right)}{\left( \frac{108}{10.6} \right)} = 0.736$
Hence, the crystal should be FCC.
