Interpretation:
The radius of Iron atom in picometers has to be calculated.
Concept Introduction:
Body-centered unit cell:
A body – centered cubic cell is a type of unit cell with atoms arranged in all the vertices of the unit cell and one atom at the center of the cube.
Figure 1
A body – centered cubic unit cell has its all the eight vertices arranged with atoms in it. Eight atoms are arranged in a simple cubic unit cell in eight vertices. Each atom in a vertex is shared by eight neighboring unit cells such that each cubic unit cell has
