The value of lattice constant a=(4r/√2) =2√2× r =2√2× 2.54/2 =3.59A

Q. Copper has face centered cubic (fcc) lattice with interatomic spacing equals to $2.54 A o$ . The value of lattice constant for this lattice is

$3 .59 A o$

$2.54 A o$

$1.27 A o$

$5.08 A o$

The value of lattice constant $a = \frac{4 r}{2}$ $= 22 \times r$ $= 22 \times 2.54/2$ $= 3.59 A$
