Feb 23, 2021 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.

Nov 04, 2019 You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple.

Oxidation state Wikipedia

The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component.

Variable valency is exhibited by:

Transitional elements exhibit variable valency as transition elements have both s electrons of outermost shell and d electrons of the penultimate shell. By losing some s and d electrons these elements can achieve intermediate stable half-filled and full filled configuration. Due to the above reason, transition elements show variable oxidation
