Adding an electron to an atom can result in one of three things. It will depend on what condition the atom starts in. For an atom that has less electrons than protons (a positive ion), it will make that atom less positive. If the atom has just one less electron than the number of protons, the additional electron will neutralize that atom. In a neutral atom, the extra electron will make that atom a negative ion. In an atom with one or more electrons than protons, that atom will be a negative ion, and the additional electron will simply make it more negative. Also, when an electron is added to a neutral atom, energy is released
You cannot add energy to an electron, as it is pure energy. However, you can add electrons from another atom to the original atom (as long as the original atom has less than eight electrons in it's outermost energy level) to create a bond between the two atoms.
The energy can be absorbed by the electron, causing it to jump to a different energy level. Later it returnd to the "ground state" and releases the energy as a particular spectrum of e-m radiation (sometimes light). This is a test used sometimes to identify the element because different elements have diffeent spectra (colors) emitted.
Sometimes the energy causes the electron to be completely removed from the atom forming a positive ion. This is called ionization energy.
when energy is added to an electron, it gains negative charge
The electrons jump to a higher orbit or level
When energy is added to an atom, the electrons move to outer levels of the shell. When they drop back down, they release the energy in the form of photons.
If an atom receives another electron, it will become an isotope of the atom, and will gain a negative charge, since there will be more electrons that protons.
It becomes an anion.
when an atom loses an energy , it loses a electron, so what exactly happens to an electron. when you are looking at the periodic tabel they are numbered in groups called group family 1-18 .for an example for what happens to an atom when it losses an electron .when a electron has a nuber lower that 4 it wants to reach at 0 electrtons and when a atom has higher than 6 elctrons it wants to reach at 8 elcrtons . when a atom losses a electron it gives it to another atom that has lower than 4 electrons who is trying to reach at 8
The energy required to remove an electron from a neutral atom is the atom's ionization energy. It represents the amount of energy needed to remove the most loosely bound electron from an atom in its gaseous state.
It becomes a positive ion.
what happen when an atom what has a lot of electron comes in contact with an atom that has gained an electron
The electron emits a photon of light which we can see in a spectrograph as color. Four colors are normally seen in a hydrogen atom subjected to energy.
the atom becomes negatively charged
when an electron is added to an atom, the atom will acquire a negative charge.
It becomes an anion.
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
It will absorb or emit energy, according to the difference in the corresponding energy levels.
The ATOM decreases in size when it loses an electron and increases when electrons are added.

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
