Valence
The outermost electron shell in an atom is called the valence shell. It contains the most reactive electrons because these electrons are involved in forming chemical bonds with other atoms.
All the components of an atom (neutron, proton, electron) are called subatomic particles or elementary particles.
The maximum number of electrons in a shell / energy level is given by 2n2.
That electron configuration represents the electron arrangement of a neutral atom of magnesium (Mg), which has 12 electrons. It shows the distribution of electrons in various energy levels or shells: 1s2, 2s2, 2p6, and 3s2.
Electrons are transferred from one reactant (reducing agent) to another (oxidizing agent). The reducing agent loses electrons (oxidation) and the oxidizing agent gains electrons (reduction). This electron transfer results in the generation of electrical energy or a chemical change in the substances involved in the reaction.

No, that electron configuration does not exist. After the 3p orbital fills with electrons, the next lowest energy orbital is 4s. After 4s contains 2 electrons, then 3d can accept electrons, upto 10. The element with this electron configuration is zinc, one of the transitional metals. Although 3d is full, those electrons can be 'valence' electrons and given to non-metals to form ions, such as Zn+2 or Zn+4. So 3d really acts like a 4th shell orbital and will still be quite reactive even when full. To see just how reactive these electrons are, look at the youtube videos embedded in this site: http://www.chemicool.com/elements/zinc.html.
"Electron cloud" is the name given to the electrons which surrounds the atomic nucleus.
The formula used to calculate the speed of electrons in a given system is v e/m, where v represents the velocity of the electron, e is the charge of the electron, and m is the mass of the electron.
Francium is an alkaline metal, which means that its one electron is easily given away, making it highly reactive. Because the atom is so large, there is a shielding effect between the protons in the nucleus, and the valence electron. This blocks the attractive forces, and the other layers of electrons work to repel the valence electron, decreasing the ionization energy even further. The low ionization energy is what makes francium so reactive, that none of it can be isolated effectively.

If an electron is given, an atom becomes negatively charged. If an electron is received, an atom becomes positively charged. This exchange of electrons leads to the formation of ions.
The maximum number of electrons in a shell / energy level is given by 2n2.
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.
Electron transitions release photons.
The electron density formula used to calculate the distribution of electrons in a given system is (r) (r)2, where (r) represents the electron density at a specific point in space and (r) is the wave function of the system.
Simply put , there are three shells of electrons around the nucleus. The innder most '1s' shett contains two electrons. The next shell has '2s' shell contains two electrons The outer most shell has '2p' shell contains 2 electrons. Overall the Carbon electron configuration is given as 1s2, 2s,2p2,
