# Explain in easy words. What does degenerate orbitals mean?

**Degenerate** means that they have the same energy. ##ns## orbitals cannot be degenerate with respect to themselves because there is only **one** ##ns## orbital for a given ##n##.

Degeneracy is defined for a selection of orbitals that are equal in energy, irrespective of quantum number, but they must be essentially equal in energy to be degenerate, and there must be at least two of them in total.

For instance, the **one** ##5s## and **five** ##4d## orbitals in yttrium (##"Y"##) may as well be considered degenerate with respect to each other, as their orbital potential energies are about ##-"6.70 eV"## and ##-"6.49 eV"##, respectively (Appendix B.9), a difference of ##"0.39 eV"##, or ##"8.99 kcal/mol e"^(-)## (##3.82%## the ##1s->2s## transition energy of the hydrogen atom).
