When an electron passes from one atom to another is a photon emitted?
rumborak said:rolotomassi, electrons are exchanged between atoms during chemical processes.
No, as a general rule, photons are not necessary part of an atom-to-atom transport of an electron. The energies involved can be all just be heat energy.
rumborak said:Phonons aren't photons. The OP question is whether every atom-to-atom transfer involves an emitted photon. It doesn't.
Photons are elementary particles that make up light. They have no mass and travel at the speed of light in a vacuum.
Photons can be created in various ways, such as through the emission of electrons in atoms, nuclear processes, or the decay of other particles.
The energy of a photon is directly proportional to its frequency. This relationship is described by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency.
Photons cannot be destroyed, but they can be absorbed by matter. When a photon is absorbed, its energy is transferred to the absorbing material, causing an increase in the energy of its atoms or molecules.
Photons are the building blocks of the electromagnetic spectrum. They have different energies and wavelengths, which determine their place on the spectrum, from radio waves to gamma rays.
