Q. Copper has face centred cubic lattice with interatomic spacing $2.5 \overset{˚}{A}$ . The value of lattice constant will be about

$0.35 \overset{˚}{A}$

$3.5 \overset{˚}{A}$

$7.0 \overset{˚}{A}$

$1.5 \overset{˚}{A}$

Lattice constant is the side of the cubic crystal.
$S = \frac{2.5}{2} \times 2$
$= 3.5 \overset{˚}{A}$
