Light.
When electrons lose energy and return to their initial state, they give off light in the form of photons. The energy of the emitted light corresponds to the energy difference between the initial and final states of the electron.
The highest energy state is the excited state, where an atom or molecule has absorbed energy and its electrons are at higher energy levels than their ground state. This state is temporary and unstable, as the electrons will eventually return to their ground state and release the absorbed energy.
An atom is in an excited state when it has absorbed energy, causing its electrons to move to higher energy levels. These excited electrons are unstable and eventually return to their ground state by emitting energy in the form of light or heat.
Electrons generally prefer to be in the ground state, which is the lowest energy level available to them. This state is the most stable configuration, as it minimizes the energy of the atom or molecule. While electrons can be excited to higher energy states, they tend to return to the ground state, releasing energy in the process.
The exciting of an electron takes in energy. The fall back to the ground state releases that energy as a photon. The photon is created by the return to the ground state.
When electrons are excited, they absorb energy and move to higher energy levels. This can happen through various processes like heat, light, or electrical energy. The excited state is temporary, and electrons will eventually return to their original energy levels, releasing the absorbed energy in the form of light or heat.
An element's electrons can be in an excited state when they absorb energy from an external source, such as heat or light. This added energy causes the electrons to move to higher energy levels further from the nucleus. As the electrons return to their original energy levels, they release this extra energy in the form of light or heat.
When the electrons of an excited atom return to a lower energy state, the energy emitted can result in the production of light, in the form of photons. This process is known as emission spectroscopy and is used in various analytical techniques to identify elements or compounds based on their characteristic emission spectra.
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
They will remain in the lower energy state, until they absorb energy once again.
Ultraviolet light has higher energy compared to visible light, which can excite electrons in certain materials to a higher energy state. When these electrons return to their original state, they release energy in the form of visible light, causing fluorescence.
