Question

Statement: Face-centred cubic structure possesses the most close packing of atoms in it.

State whether the given statement is true or false

• A. True
• B. False

Answer 1

The correct option is A True

Unit cell	Number of atoms at			No. of atoms per unit cell	Volume occupied by particles $\left(\%\right)$
	Corners	Centres	Faces
Simple cubic	$8\times \frac{1}{8}=1$	0	0	1	52.4
Body centred cubic (BCC)	$8\times \frac{1}{8}=1$	1	0	2	68
Face centred cubic (BCC)	$8\times \frac{1}{8}=1$	0	$6\times \frac{1}{2}=3$	4	74
