When electron hits any wall like thing will it lose all its energy?

The electron does not lose its energy. The electron gets absorbed by the "wall" and the electron/energy becomes part of the "wall" system.

Is an electron and photon the same thing. It seems like my book interchanges them for one another. I'm confused?
No. The electron is not a photon. An electron is a charged particle of matter. A photon is a unit of "energy-time" designated by Planck's Constant h.
Does the same electron move in the whole circuit?
No. It is more like one electron bumping into the next electron - passing along its energy.
Hydrogen is grouped with alkali metals because it?
it has one electron in its outer energy level like all alkali metals
What happens to an electron if it is given energy?
An electron emits energy in the form of an x-ray (a photon) when its energy level in the electron cloud decreases as a result of reduction in the excitation level of the cloud. This means that the position of the electron in the cloud changes to a lower level.
What are like shelves where electrons are found?
orbits are like energy levels where probability of finding electron is maximum
Why is it that sometimes when a very high energy electron hits a target material a positron and two or more electrons come out of the event?
An electron at high energy entering into a scattering event will bring all that energy with it. All that energy will have to be "dealt with" in the outcome. One way that a big chunk of it can be "handled" is almost magical. A large portion of the energy can be transformed into an electron-positron pair. This event is called pair production. We usually see it when a high energy gamma ray causes it, but it can be one of the outcomes in an energetic electron collision. The production of this pair of particles is the direct result of the conversion of energy into matter, and it will carry off a lot of the energy in the event. The minimum energy need to create the pair is 1.022 MeV. The original electron is still "in one piece" after the event, so it may look like the single electron crashed into a target and two electrons and a positron came away. It was actually the original electron and that electron-positron pair. If the original electron ionized another electron (or more) in the target material (which is possible), they will come away as well. Certainly there are a number of possible outcomes in an energetic electron scattering event, but pair production is one of the possible outcomes, depending on the energies involved and the target material.
Why do high-energy electrons need carrier molecules?
The energy in light raises some of the electrons in chlorophyll to higher energy levels. These high-energy electrons are used in photosynthesis. Electron carriers are used to transport the electrons from chlorophyll to other molecules during photosynthesis.
What is the lowest energy excited state electron configuration of O2?
The electron configuration for an O2- ion is 1s22s22p6 just like the noble gas neon.
What are the difference between energy levels and energy states?
These terms are used to describe quantum particles like atoms. Energy level and energy state are used interchangeably, however, specifically energy level is used to describe physically where an electron is located in an atom and energy state describes the definite activity of the electron. Since the activity of an electron will dictate its location, this is where the terms become to mean nearly the same thing.
Why does sodium vapor emit only certain frequencies of visible light?
It is because the electrons surrounding an atom, say sodium, can only exist at certain energy levels. When a photon (packet of light energy) hits an orbiting electron it only gives energy to that electron if the energy of the photon is exactly enough to move the electron to a higher energy level, if not it doesn't effect the electron. As the energy of a photon is directly proportional to the it wavelength, only certain wavelengths affect an atom's electrons. When they do effect the electrons the photon is absorbed, giving the absorption spectrum. Emission spectra are the reverse of this process, when an electron cascades back down to its lowest possible energy state after this photon interaction it gives out certain frequencies of light. The energy of this light will be equal to the energy absorbed, so the photons emitted will be equal to the photons absorbed which is why emission spectra look like the inverse of an absorption spectrum.
Is current return through the neutral?
yes but the load like any thing , the use of electron
Would an electron have to absorb or release energy to jump from the second energy level to the third level?
Electrons are attracted to the nucleus of the atom of which they are a part; this is because of the electrostatic force between the negatively charged electron and the positively charged nucleus. Therefore it takes energy in order to pull an electron farther away from the nucleus and to enable it to remain at a greater distance. This is exactly the same phenomenon as raising a heavy object such as, let us say, a bowling ball, to a greater elevation. It takes energy to do it, since you have to overcome the force of gravity.
