What else can I help you with?
Can free electron absorb photon?
Yes, free electrons can absorb photons. When a photon interacts with a free electron, it can transfer its energy to the electron, causing it to move to a higher energy level or even be ejected from the material. This process is the basis for various phenomena such as photoelectric effect and Compton scattering.
Compton scattering is defined as what?
Compton scattering is an inelastic scattering of a photon by a free charged particle, usually an electron. It results in a decrease in energy of the photon.
What is an escaped electron called?
An escaped electron is called a FREE electron, simple as that. It means: not bound or belonging to a particular atom (or ion)
Is there any situation where an electron will have a charge not quantized ExOutside of an atom and if so what would happen if it had exess energy when it goes to an orbit?
The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
What are the two easily detectable products of the decay of a free neutron?
A free neutron decays into a proton, an electron and an electron neutrino (with a mean lifetime of about 15 minutes). Of these, the proton and electron are readily detectable. Neutrino detection is extraordinarily difficult.
Can free electron absorb photon?
Yes, free electrons can absorb photons. When a photon interacts with a free electron, it can transfer its energy to the electron, causing it to move to a higher energy level or even be ejected from the material.

Compton scattering is defined as what?
Compton scattering is an inelastic scattering of a photon by a free charged particle, usually an electron. It results in a decrease in energy of the photon.
Is there any free charge on photon?
No. Otherwise it wouldn't be a photon.
What is a radical containing nitrogen and oxygen?
a radical is a free electron, therefore it cannot be nitrogen or oxygen, its just an electron
Why conversion of a photon to an electron positron pair is not possible in free space?
Because energy mass conservation will not be satisfied in free space, so that this process needs some material by which this conversion will be proceed.
Why can't an electron in a photoelectric effect event absorb more than one photon?
Because it can't. It's a one-at-a-time thing. That's what quantum mechanics is based on. If a photon arrived at a "possible reaction site" and it isn't the "right" energy (it's energy is too high or too low) to cause the event to happen, it won't happen. And if two arrive at the correct energy, only one participates. It's like the little guys formed a "back room deal" as to what and how they were going to interact! Things happen one at a time owing to the "will" of the participants. Quantity control is a reality of quantum mechanics. The photons and electrons don't want it any other way (by their very natures), so it won't happen any other way. They refuse any other offers.
How can an electron be easily removed?
An electron can be easily removed by supplying it with enough energy to overcome the attraction of the nucleus, causing it to break free from the atom. This can be achieved through processes such as ionization, where an external source like a photon or electric field interacts with the electron, causing it to be ejected from the atom.
What is different between free electron and inner shell electron?
A free electron is able to move as it is in the outer shell of the atom. So free electrons can carry a charge. If an atom has free electrons it is able to conduct electricity. Inner shell electrons cannot carry a charge as they are closer to the nucleus.
Does the Pauli equation predict spin for a free particle ie not in a field?
Fundamental particles such as the electron or the photon have an intrinsic spin, and this spin can't change - for example, an electron always has a spin of 1/2. I don't think the Pauli equation would change that.
Free-electron theory of metals is used for?
write note on free electron theory
Why does the free electron theory fail to predict the semiconducting properties of materials?
Drawbacks of Classical free electron theory:1. It is macroscopic theory2. This theory cannot explain the electron conductivity ofsemiconductors and insulators.3. Ferromagnetism cannot be explained by this theory.4. This theory cannot explain the Photoelectric effect, Comptoneffect and the Black Body radiation.5. The calculated value of specific heat of metals is not matchingwith the experimental value.6. At low temperature, Lorentz number is not a constant. But by12classical theory it is a constant.7. Dual nature cannot be explained.8. Atomic fine spectra cannot be explained.9. Classical theory states that all the free electrons will absorbenergy, but quantum theory states that only few electrons willabsorb energy
What is the difference between free electron theory and nearly free electron theory?
free electron model not take into account the potential neither the electron interaction. nearly free electron take into account the potential.J.C. Aguiar
