We all know that the chemical formula for water is H 2 O. What is the reason for this particular formula? Let us know more about Valency and how it helps in determining a formula! Valency is the measure of the combining capacity of atoms or molecules. Therefore, it is the capacity of an atom of a single element to react and combine with particular numbers of atoms of another element. Electrons in an atom are arranged in different orbitals shells represented as K, L, M, N, and so on.

On a chemical level, an important clue to the unraveling of the electronic structure of atoms is the existence of noble gases, which are almost completely unable to form chemical compounds. This lack of reactivity suggests that the atoms of these elements have structures which do not permit interaction with the structures of other atoms. A second clue is the close correspondence between the valence of an element and the extent to which its atomic number differs from that of the nearest noble gas. Elements which have a valence of 1 , for instance, have atomic numbers one more or one less than that of a noble gas. Similar remarks apply to a valence of 2. The alkaline-earth metal atoms Be, Mg, Ca, Sr, and Ba all contain two electrons more than a noble-gas atom, while the elements O, S, Se, and Te all contain two electrons less.

The valence electrons take part in any chemical reaction because the outermost orbit usually contains more energy than the electrons present in other orbits.
