Electrons do not "spend" energy in the classical sense when moving through their orbitals, as each orbital corresponds to a specific energy level. They gain kinetic energy from electric fields but do not lose energy unless acted upon by external forces, such as when they emit photons. The concept of electrons moving around the nucleus is more accurately described by wave functions, indicating probabilities rather than classical paths. If electrons were to move like planets, they would continuously emit energy, which does not occur in stable atomic orbitals. Overall, the discussion emphasizes the distinction between classical and quantum mechanical views of electron behavior.
