Lithium forms body centred cubic structure. The length of the side of its unit cell is 351 pm. Atomic radius of the lithium will be

75 pm

300 pm

240 pm

152 pm

Solution

152 pm

In body centred cubic structure,
Edge length = a = 351 pm, radius= r=?
$straight r space equals space fraction numerator square root of 3 straight a end root over denominator 4 end fraction space equals fraction numerator square root of 3 space straight x space 351 over denominator 4 end fraction space equals space 152 space pm$
