How to electrons move from one orbital to another in atoms?

Electrons can move between orbitals by releasing or absorbing energy.

Explanation:

When an electron absorbs energy, it jumps to a higher orbital which is known as excited states. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy. The energy contained in that photon corresponds to the difference between the two states the electron moves between. When the electron returns to the ground state, it can no longer release energy but can absorb quanta of energy and move up to excitation states/higher orbitals.
