What do you mean by Exchange Energy?

Understanding the concept:

• The exchange interaction, a quantum mechanical phenomenon, only occurs between identical particles.
• Exchange energy is released when two or even more electrons of the same spin change places in a subshell's degenerate orbitals.

Importance of exchange energy:

• Electrons with the same spin tend to interact with one another when they are located in distinct orbitals with the same energy.
• This lowers the atom's energy.
• Interchange energy is the term for the decrease in energy caused by the exchange of electrons in orbitals with the same energy.
• This improves the stability of an atom.
