When an electron gains energy, it can move to a higher energy excited state. This process involves the electron transitioning from its original energy level, known as the ground state, to a higher energy level because of the absorption of energy. This excited state is not permanent; the electron may eventually return to its ground state, releasing energy in the form of light or heat.

The phenomenon of an electron moving to a higher energy level is fundamental in quantum mechanics and explains many key concepts in chemistry and physics, such as the behavior of atoms and the emission and absorption spectra of elements. This transition underpins how atoms interact with energy, ultimately influencing chemical bonds and reactions.

In contrast, remaining in the ground state does not occur upon gaining energy, as the energy absorbed would prompt a change. Skipping to the nucleus is not a possible action for an electron, as electrons occupy defined energy levels around the nucleus. Lastly, instantly losing all energy is not a viable process; energy changes occur gradually and through specific interactions, not as an instantaneous event.
