The exchange interaction is a quantum mechanical phenomenon that only takes place between identical particles in chemistry and physics.
The energy produced when two or more electrons with the same spin switch places in the degenerate orbitals of a subshell are known as exchange energy.
Definition:
It can be explained by the parallel spin and propensity for position switching of the electrons in degenerate orbitals.
The energy produced when two or more electrons with the same spin switch places in the degenerate orbitals of a subshell are known as the exchange energy.
The greatest number of exchanges occurs when the orbitals are half- or fully filled. Its stability is therefore at its highest.
