Can Atoms Produce Photons Through Electron Excitation?

In summary, atoms do not contain photons, but they can produce them through various processes. When electrons fall from higher to lower energy levels, the energy is released as a photon. This can also occur when the nucleus is excited or when electrons are deflected or accelerated in a magnetic field. So, electrons are responsible for the production of photons in atoms.

I know that 'When electrons get excited, they release photons to "un-excite".'
So how can a atom 'produce' photons?

Photons are energy.
When an electron falls from a high energy level to a lower one the energy is released as a photon.
The atom doesn't contain a photon as such.

this is probably one of the most asked quetions around here, please feel free to search for older threads =)

Atom as a whole dont't emit photons. Photon emission occurs when electron jumps from higher to lower energy level. Photon can also be produced by exciting the nucleus (remember internal conversion)...however in both the cases electrons are responsible for photon emission. Also when you deflect or make electron to accelerate in magnetic field...you can get photons.

1. Do atoms actually create photons?

No, atoms do not create photons. Photons are fundamental particles that are emitted or absorbed by atoms during a change in energy state.

2. How do photons interact with atoms?

Photons interact with atoms through the electromagnetic force. When a photon collides with an atom, it can be absorbed, reflected, or scattered depending on the energy of the photon and the energy levels of the atom.

3. Can atoms emit photons without any external influence?

Yes, atoms can emit photons without any external influence through a process called spontaneous emission. This occurs when an excited atom spontaneously returns to a lower energy state and emits a photon.

4. Can photons be created from sources other than atoms?

Yes, photons can be created from sources other than atoms. For example, they can be created through particle interactions, such as in a particle accelerator, or through nuclear reactions.

5. How do atoms create light?

Atoms create light by emitting photons. When an atom absorbs energy, it can become excited and move to a higher energy state. As the atom returns to its ground state, it releases the excess energy in the form of a photon, which is a packet of light.
