What do you mean by Exchange Energy?

In chemistry and physics, the exchange interaction is a quantum mechanical effect that only occurs between identical particles. Exchange energy is the energy released when two or more electrons with the same spin-exchange their positions in the degenerate orbitals of a subshell.

Definition

It can be defined as the electrons which are there in degenerate orbitals have a parallel spin and tend to exchange their position.

The exchange energy is the energy released when two or more electrons with the same spin-exchange their positions in the degenerate orbitals of a subshell. Exchange energy is nothing but the energy released during this process. When the orbitals are half-filled or completely filled then the number of exchanges is maximum. Therefore, its stability is maximum.
