A solid has a bcc structure. If the distance of closest approach between the two atoms is $1.73 Å$ . The edge length of the cell is:

Options:

Answer:

Solution:

Also closest appraoch in bcc lattice is $\frac{1}{2}$ of body diagonal,

i.e. $\frac{\sqrt{3}}{2} a$

Or $a = \frac{1.73 \times 2}{\sqrt{3}} = 1.996 Å = 199.6 p m$
