Sodium metal crystallizes is body centred cubic (BCC) lattice with cell edge $(a) = 4.29 Å$ . The radius of sodium atom is

Options:

Answer:

Solution:

In BCC lattice atomic radius (r) of Na is given by

$r = \frac{\sqrt{3}}{4} \times a = \frac{\sqrt{3}}{4} \times 4.29 Å = 1.86 Å$

$= 1.86 Å \times \frac{1 0^{- 10} m}{1 Å} \times \frac{1 p m}{1 0^{- 12} m} = 186$ pm
