What is Degenerate?
In chemistry and quantum mechanics, degenerate refers to two or more quantum states (orbitals, energy levels) that have the same energy. For example, the three 2p orbitals (2px, 2py, 2pz) are degenerate in an isolated atom — they have the same energy. Degeneracy is lifted when the symmetry is broken (e.g., in a crystal field or magnetic field), leading to energy level splitting.
