Why can two #s# orbitals NOT be degenerate?
2 Answers
Two or more orbitals are degenerate if they have the same energy.
Degenerate means that they have the same energy.
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
