The image above represents planar density. To calculate planar density, two essential parameters are needed and these parameters are Number of Atoms Centered on the Plane (N) and Area of the Plane (A).
The formula for calculating planar density:
PD =Â N/A
Where:
PD = Planar Density
N = Number of Atoms Centered on the Plane
A = Area of the Plane
Given an example;
Find the planar density when the number of atoms centered on the plane is 24 and the area of the plane is 3.
This implies that;
N = Number of Atoms Centered on the Plane = 24
A = Area of the Plane = 3
PD =Â N/A
So, PD = 24/3
PD = 8
Therefore, the planar density is 8 atoms/m².
Calculating the Number of Atoms Centered on the Plane when the Planar Density and the Area of the Plane are Given
N = PD x A
Where:
N = Number of Atoms Centered on the Plane
PD = Planar Density
A = Area of the Plane
Let’s solve an example;
Find the number of atoms centered on the plane when the planar density is 4 and the area of the plane is 10.
This implies that;

PD = Planar Density = 4
A = Area of the Plane = 10
N = PD x A
Then, N = 4 x 10
N = 40
Therefore, the number of atoms centered on the plane is 40 atoms.
Calculating the Area of the Plane when the Planar Density and the Number of Atoms Centered on the Plane are Given
A = N / PD
Where:
A = Area of the Plane
PD = Planar Density
N = Number of Atoms Centered on the Plane
Let’s solve an example;
Find the area of the plane when the planar density is 10 and the number of atoms centered on the plane is 70.
This implies that;
PD = Planar Density = 10
N = Number of Atoms Centered on the Plane = 70
A = N / PD
So, L = 70Â / 10
L = 7
Therefore, the area of the plane is 7 m².
