Electron excitation

Electron excitation occurs when an electron in an atom absorbs energy, causing it to move from a lower energy level to a higher one. This added energy can come from heat, light, or electricity. Once excited, the electron is in an unstable state and will eventually return to its original level, releasing energy in the form of light or heat. This process is essential in various phenomena, such as the colors we see in fireworks or the way fluorescent lights work. Understanding electron excitation helps explain many natural and technological processes.
