Question

what is the relation between r&d in simple cubic unit cell ​

Answer 1

Answer:

The relationship between atomic radius and edge length in a unit cell depends on the type of the cell. → If l is the edge length, then 2*r =l or r = l/2 , where r is the radius of the atom. A BCC unit cell has atoms at each corner of the cube and an atom at the center of the structure.
