A valence electron is anelectronthat is the most likely to be involved in a chemical reaction. They are typically the electrons with the highest value of theprincipal quantum number,n. Another way to think of valence electrons is that they are the outermost electrons in an atom, so they are...

The meaning of VALENCE is the degree of combining power of an element as shown by the number of atomic weights of a monovalent element (such as hydrogen) with which the atomic weight of the element will combine or for which it can be substituted or with
It is important to realize that the valence electron concentration is not the only factor which influences crystal structure and consequently blind application of the. valence electron concentration rules is bound to lead to confusion.XXIVth International Congress of Pure and Applied Chemistry...
radius. It is determined by the equation: (-eV) =kn/r. 'k' is a proportionality factor converting�ngstromsinto centimeters and expressing the force exerted by the valence electrons in electron volts which is equated to 14.399. 'n' is the valence. 'r' is the ionic radius in �ngs...
Valence, in chemistry, the property of an element that determines the number of other atoms with which an atom of the element can combine. Introduced in 1868, the term is used to express both the power of combination of an element in general and the nume
Valence electron, any of the fundamental negatively charged particles in the outermost region of atoms that enters into the formation of chemical bonds. Whatever the type of chemical bond (ionic, covalent, metallic) between atoms, changes in the atomic s

absorbed either by a direct photoelectron event of a valence band electron or by exciting a core electron into an empty conduction band state. In the latter case, the atom may relax by filling the core hole with an electron from the valence band and emit an electron from the valence band....
