Valence
It is the valency shell.
Electrons may be transferred from one particle to another.
An electron configuration refers to the distribution of electrons in orbitals. Since there are no ions given for this question, an electron configuration cannot be provided.
The maximum number of electrons in a shell / energy level is given by 2n2.
If an atom has equal number of protons and electrons it is neutral.If electrons are given out it has a possitive charge.If electrons are gained it has a negative charge.This way atoms become chemically stable.

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.
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.
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.
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,

Ionosphere
In metallic bonding, the valence electrons freely 'jump' from atom to atom, forming kind of an electron sea.
Electricity is the name given to the flow of electrons. Conventionally, the electrons flow from the negative terminal to the positive. An individual electron does not make the whole trip instantaneously - an electron moves on to an atom, which then has an excess of charge, and the spare electron is passed on to the next atom, and so on.electrons are charged particles and the flow of these electrons constitute electricity.
