Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
Protons and neutrons have approximately the same mass, but the proton is electrically charged and the neutron isn't. Electrons have a much much lower mass and an opposite electrical charge to that of the proton. That's about as simple as I can get it. It's by no means the only difference between them.
W-bosons are charged and the photons are uncharged, W-bosons have a non zero rest mass and photons hsve zero rest mass. Also the W-boson is the "exchange particle" in interactions involving the weak nuclear force, but photons are the exchange particle of the electromagentic force.
Wht is the difference between Lanthanides and Actinides?
Inside an atomic nucleus, there are protons and neutrons. Due to the nature of how they must interact, they are constantly changing back and forth between each other. Electrons, however, which are found outside of the nucleus, do not change.
chemical deviation
Electrons can only absorb photons that have energy equal to the energy difference between two allowed energy levels in the atom or molecule.
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
The photoelectric effect involves the ejection of electrons from a material when it absorbs photons, while Compton scattering is the process where photons collide with electrons, causing them to change direction and lose energy. The key difference is that in the photoelectric effect, electrons are ejected from the material, while in Compton scattering, electrons remain within the material but change their direction and energy.
The amount of energy given off by excited electrons when they radiate energy is equal to the difference in energy level between the initial and final states. This emitted energy is typically in the form of photons.
The photoelectric effect involves the ejection of electrons from a material when photons of sufficient energy are absorbed, while the Compton effect involves the scattering of photons by free electrons in a material, resulting in a change in the photon's wavelength. In the photoelectric effect, photons interact with electrons in the material, leading to the ejection of electrons, while in the Compton effect, photons collide with free electrons, causing them to scatter and change direction.
When the electrons of an excited atom fall back to lower levels, they emit energy in the form of photons. These photons can have specific frequencies corresponding to the energy difference between the initial and final electron energy levels, leading to the emission of light in various forms such as visible, ultraviolet, or infrared light.

No. Electricity is the movement of electrons, and photons have no electrons to move. Photons are the gauge particles for the electromagnetic force, but that's a different concept.
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.
In the reverse photoelectric effect, electrons are accelerated through a potential difference and strike a metal target, resulting in the production of photons. The kinetic energy of the incident electrons is converted into electromagnetic radiation when they hit the target, creating photons with energy corresponding to the kinetic energy of the electrons. This phenomenon is the basis for X-ray generation in X-ray tubes.
Yes, photons are smaller than electrons. Photons are elementary particles that have no mass and are considered to be point-like particles, while electrons have mass and are considered to be fundamental particles with a measurable size.
When atoms emit light, their electrons move to lower energy levels, releasing the excess energy in the form of photons. The photons emitted have a specific wavelength corresponding to the energy difference between the initial and final electron levels. This process is known as emission of light or photon emission.
