WebMar 22, 2024 · Valency is the maximum number of electrons that an atom loses, gains or shares to become stabilized during a chemical reaction. As shown in the above image of water molecule (H 2 O), each of the two hydrogen atoms (H) shares one electron with the oxygen atom. In other words, the hydrogen atom loses one electron to become stable.
