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.
What else can I help you with?
What is the difference between regular electrons and valence electrons?
electrons*
What happens to atoms and their electrons while the entity emits light?
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.
Which subatomic particle of the atom in a molecule interacts with photons?
Electrons are the subatomic particles in an atom that interact with photons. When photons interact with electrons, they can be absorbed, emitted, or scattered, leading to various chemical and physical processes in a molecule.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
What were the four principles of the bohr model?
The four principles of the Bohr model are: electrons orbit the nucleus in fixed energy levels or shells, electrons can jump between different energy levels by either absorbing or emitting photons, angular momentum of electrons is quantized, and the frequency of emitted or absorbed light is directly related to the energy difference between electron levels.
Electrons can only absorb photons that have energy equal to what?
Electrons can only absorb photons that have energy equal to the energy difference between two allowed energy levels in the atom or molecule.
What is the difference between photons and electrons?
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.
What are the differences between the photoelectric effect and Compton scattering in terms of their interactions with photons and electrons?
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.
When excited electrons radiate energy the amount of energy given off is equal to?
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.
What are the differences between the photoelectric effect and the Compton effect in terms of their interactions with matter and the behavior 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 there is an emission of energy that produces what?
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.
What is the difference between regular electrons and valence electrons?
electrons*
Do photons conduct electricity?
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 what is given off?
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.
How photons are generated by reverse photelectric effect?
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.
Are photons smaller than electrons?
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.
What happens to atoms and their electrons while the entity emits light?
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.
