Calculate planer density of 110 plane in BCC?

The planar density of the (110) plane in a body-centered cubic (BCC) structure can be calculated using the formula:

[ \text{Planar Density} = \frac{\text{Number of atoms centered on the plane}}{\text{Area of the plane unit cell}} ]

In the (110) plane, there are 2 atoms per unit cell, and the area of the (110) plane can be determined as ( \sqrt{2}a^2 ), where ( a ) is the lattice parameter. Thus, the planar density for the (110) plane in BCC is calculated to be ( \frac{2}{\sqrt{2}a^2} = \frac{\sqrt{2}}{a^2} ) atoms per unit area.
