Question

Exchange energy of an electron is the energy released when it exchanges its position with?

• A. The electron having opposite spin in present in non-degenerate orbitals
• B. The electron having same spin present in degenerate orbitals
• C. The electron having same spin present in non-degenerate orbitals
• D. The electron having opposite spin present in degenerate orbitals

Answer 1

The correct option is B The electron having same spin present in degenerate orbitals

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.
