The image above represents the potential between atoms. To calculate the potential between atoms, three essential parameters are needed, and these parameters are the Separation Distance of Atoms (δ), the Radius of Atoms (r) and the Energy Parameter (ε).
The formula for calculating potential between atoms:
φ(r) = 4ε[(δ/r)12 – (δ/r)6]
Where:
φ(r) = Potential between Atoms
δ = Separation Distance of Atoms
r = Radius of Atoms
ε = Energy Parameter
Let’s solve an example;
Find the potential between atoms when the separation distance of atoms is 14, the radius of atoms is 18 and the energy parameter is 22.
This implies that;
δ = Separation Distance of Atoms = 14
r = Radius of Atoms = 18
ε = Energy Parameter = 22
φ(r) = 4ε[(δ/r)12 – (δ/r)6]
That is, φ(r) = 4(22)[(14/18)12 – (14/18)6]
φ(r) = 4(22)[(0.77)12 – (0.77)6]
φ(r) = 88[0.049 – 0.22]
So, φ(r) = 88[-0.172]
φ(r) = -15.168
Therefore, the potential between atoms is -15.168 V.
