Question

if the radius of an atom of an element is 75pm and the lattice type is BCC.what is the edge of unit cell​

Answer 1

Answer:

For body centered cubic lattice, the relationship between the edge length a and the radius r is as given below:

a=

3

4r

Substituting values in the above expression, we get

a=

3

4×75

=173.2 pm

Hence, the edge length of the unit cell is 173.2 pm.
