- excitation, in physics, the addition of a discrete amount of energy (called excitation energy) to a system—such as an atomic nucleus, an atom, or a molecule —that results in its alteration, ordinarily from the condition of lowest energy (ground state) to one of higher energy (excited state).

Excite is an American website (historically a web portal) operated by IAC that provides outsourced internet content such as a metasearch engine, with outsourced weather and news content on the main page. As of 2024, all of Excite's operations are controlled by services outside of the business.
Electron excitation is the transfer of a bound electron to a more energetic, but still bound state. This can be done by photoexcitation (PE), where the electron absorbs a photon and gains all its energy [1] or by collisional excitation (CE), where the electron receives energy from a collision with another, energetic electron.

Feb 20, 2022 · Excited helium atoms easily de-excite by transferring energy to neon in a collision. A population inversion in neon is achieved, allowing lasing by the neon to occur. There are many medical applications of lasers.
when an electron absorbs energy (from light, heat, or otherwise) it jumps to a higher energy level, or shell. Then when the electron loses that energy, it reverts back to a lower-numbered shell. Now that the atomic orbital model is now more widely accepted, how does the above concept relate to it? Figure 2.
