Is a photon an electron or proton?
Photon is a fundamental particle whose nature differs from electron, proton or positron-anti particle of electron. Photon can knock out electron from atom in photoelectric effect,scatter an electron in Compton effect and can produce electron positron pair in pair production.
Is a photon made from an electron?
A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. A sodium vapor light energizes sodium atoms to generate photons. A sodium atom has 11 electrons, and because of the way they’re stacked in orbitals one of those electrons is most likely to accept and emit energy.
Is a photon a lepton?
A photon is massless, has no electric charge, and is a stable particle. In a vacuum, a photon has three possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero.
Are neutrinos photons?
A photon is a boson, a neutrino is a fermion and also a lepton. So they are completely different particles.
What type of particle is an electron made of?
Electrons are a type of particle called leptons, and are thought to be fundamental particles – in other words, there are no particles that make up electrons. Protons and neutrons, however, are not fundamental particles – they are made up of quarks.
What is the relationship between a photon and an electron?
The photon has a frequency, or color, that exactly matches the distance the electron falls.” 1 The reverse process, i.e., when an electron moves to a higher orbital (shell), happens when a photon impacts with an atom, i.e., the atom absorbs external energy.
What is the difference between an electron and a proton?
The electron is only one member of a class of elementary particles, which forms an atom. The protons are positively charged, massive particles that are located inside the atomic nucleus. Protons were discovered by Ernest Rutherford in the year 1919, when he performed his gold foil experiment.
What is the difference between light and photons in chemistry?
Light and Photons. “An electron has a natural orbit that it occupies, but if you energize an atom you can move its electrons to higher orbitals [shells]. A photon of light is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit.
