Web$\begingroup$ Because a photon doesn't actually "collide" with an electron. Rather, the electron absorbs the energy of the photon. Rather, the electron absorbs the energy of the photon. If the energy exceeds … WebThe electron absorbs the photon and is then ‘removed’, or it goes to a. not shown energy level. This is because, it is not at the point of ionization yet (which is 13.6. eV) There are several energy levels for hydrogen that are not shown in this Gizmo. The electron. is in one of these energy levels. 7.

WebAccording to Compton Scattering a free electron can never absorb a complete photon. It has to give away a minimum energy whose wavelength is given by. lambda' = lambda° + 2h/ (m×c) Where m is mass of electron and c is speed of light. A bound electron can absorb a complete photon as we see in photoelectric effect. WebSep 3, 2024 · The electron does not absorb a photon. (I am ignoring the issue of "soft photons" mentioned in one of the answers linked by the OP, which in my opinion not related to the question the OP is asking). A Hydrogen atom consisting of an electron orbiting a proton can absorb a photon. This will happen if the photon's energy is close to one of a ...

WebDec 18, 2024 · The photon generated by the first electron transition meets with another atom and is scattered. In that process an electron in the second atom could, in theory, absorb all the energy of the photon, move into an excited state, then decay down to a lower state emitting photon(s) in the process.

WebFeb 1, 2024 · 2. Photon is spin 1 and electron is spin 1/2, so when a photon is absorbed by an electron it is destroyed and the electron becomes excited by that amount of energy. The next moment the electron will go back to it's ground state and emits a photon with the same energy as the original and everything seems good so far. body glove inflatable surfboard costcoWebDec 22, 2015 · 3 Answers.
