When an electron in an atom goes from a high energy state to a low one what occurs?

When an electron in an atom transitions from a high energy state to a low energy state, it releases energy in the form of electromagnetic radiation, typically as a photon. This process is known as emission. The energy of the emitted photon corresponds to the difference in energy between the two states, resulting in specific wavelengths of light characteristic of the atom. This phenomenon is fundamental to understanding atomic spectra and the behavior of electrons in atoms.
