Final answer:
The energy consequence of moving an electron from an outer shell to an inner shell is the release of energy, as the electron emits the energy difference between the two shells, which aligns with the law of conservation of energy.
Step-by-step explanation:
The energy consequence of moving an electron from an outer shell to an inner shell results in the release of energy. When an electron drops from a higher energy shell to a lower energy shell, the energy difference between the two shells is emitted as electromagnetic radiation, often in the form of a photon. This is because the lower energy shells are closer to the nucleus and thus have lower potential energy. To move an electron to a higher shell, energy must be absorbed; conversely, when the electron falls back to its original, lower energy state, that same amount of energy is emitted. This is consistent with the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.
