Question

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:, 200 p m, 3 2 p m, 142.2 p m, 2 p m

MARKS App · Accepted Answer

Also closest appraoch in bcc lattice is 1 2 of body diagonal, i.e. 3 2 a Or a = 1.73 × 2 3 = 1.996 Å = 199.6 p m
