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 is the name given to the electron in the highest occupied energy level?
Valence.
What happens when an electron emits a photon?
When an electron absorbs a photon, the energy it gains can cause it to change orbitals. The result is ionization. The electron can then emit a photon in the process of "falling back" into its original orbit. Note that electrons won't absorb a photon that cannot give them enough energy to reach a higher orbital. There are no "half measures" in this aspect of quantum mechanics as electrons cannot be shifted "half way" to the next higher orbital. The proof of the pudding here is that we can use lasers of a given frequency to stimulate the electrons in orbit around given atoms. By knowing how much energy a certain electron needs to move to the next higher orbital, we can tune our laser to that photonic energy. Then when we point our laser at a bunch of these atoms, we'll see a bunch of electrons being kicked up to higher orbitals and then emitting photons to return to their previous orbital. There is a bit more to this, but the essentials are here, and are a first step to understanding the subtle ways photons and electrons interact.
Will an electron excite if it is given energy that will allow it to exist in between two energy levels?
Will an electron excite if it is given energy that will allow it to exist in between two energy levels? No An electron can only exist in specific energy levels. Giving an electron more energy can make it escape from the attraction of the protons completely and the atom now has 1 less electron and is a +1 ion. Have you seen an electron discharge tube? If I turn up the power, the tube will become brighter, but the color will not change. The color of light is the product of the electron returning from the excited state to its ground state.

What is the difference between electron negativity and electrons affinity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
What is a high energy electron given off during radioactive decay called?
Beta Particles

The energy given up by electrons as they move through the electron transport chain is used to?
A good portion of the energy from the electron movement is used to pump H+ across a gradient.
Explain how the wavelengths of light emitted by an atom provide information about electron energy levels?
We know what a wavelength is, and when we apply the term to the phenomenon of electron energy levels, something amazing happens. Let's review by looking at atomic structure for a moment and take off from there. We know that electrons form up in orbitals and shells around an atomic nucleus. These orbitals are defined as energy levels, and an electron is said to be in a given energy level. When electrons get just the right amount of energy, they can "jump" to a higher energy level. There are places that they cannot go, but there are other places that are "just right" for an electron from that particular starting energy level. A specific quantity of energy (a quantum, perhaps) is the key to electrons changing energy levels. If an electron is "bumped" to a higher energy level because it has "accepted" a packet of energy that is just right, it moves up to that energy level. But it cannot stay there, so it "falls back" to where it came from. In returning to its original energy level, it must "give up" the exact amount of energy that it took to move up. This specific amount of energy translates into radiated electromagnetic energy of a given wavelength or frequency. And each wavelength corresponds to a given amount of energy. Let's apply this and see what happens. Should we consider a bunch of atoms of a given kind, they will have a specific electron structure. The electrons of these atoms "live" in given energy levels. If we excite these atoms with the right amounts or quanta of energy, the electrons that will only respond to that amount of energy will move to a higher energy level. Then the electrons will return to their original levels, giving up that wavelength of energy when they drop down. If the wavelength of electromagnetic energy is in the optical band, visible light will appear. The atoms will "glow" at a specific color associated with the wavelength of the energy that is released when those electrons return to their original energy levels. If those atoms in our experiment are a gas and we apply sufficient voltage, the gas atoms will ionize and the gas will glow. Electrons are accepting energy quanta, are moving to higher energy levels, and are then returning to their original energy levels by releasing visible light of a given color. Electron energy levels are directly related to wavelengths of electromagnetic radiation.
What happens when a 3s electron becomes a 2s electron?
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
What is the difference between an electron donor and electron acceptor?
Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.
What are the two main forms of energy given off when paper burns and where does the energy comes from?
heat and light and it comes from the reaction of the paper material and its combustion in the air.
