Answer:
True. When an electron in an atom drops down from a higher energy level (or electron shell) to a lower energy level, it releases energy in the form of light. This process is known as "emission" or "de-excitation." The energy released corresponds to the difference in energy between the initial and final energy levels of the electron, and this energy is emitted as a photon of light. This phenomenon is the basis for various optical and spectroscopic techniques used in chemistry and physics.
