The radius of an atom is 100 pm. If this element crystallizes in FCC lattice, the edge length of unit cell is

Options:

Answer:

Solution:

For FCC structure
$a \sqrt{2} = 4 r$
So $a = \frac{4 r}{\sqrt{2}} = \frac{4 \times 100 p m}{\sqrt{2}}$
$= \sqrt{2} \times 100 p m = 1.414 \times 100$ pm
$= 141.4$ pm
