Valency of oxygen: Oxygen has 6 valence

Oxygen has 6 valence electrons and it needs 2 more electrons to achieve octet. The number of electrons needed to complete octet is termed as the valency of an element. This value can be obtained by subtracting the number of valence electrons from octet (8). So, the valency of Oxygen is 2. That means Oxygen is ready to share its 2 valence electrons or ready to accept 2 more electrons in order to achieve octet. The valency of oxygen is 2 because its outermost shell contains 6 electrons and it needs 2 more electrons to attain a stable electron configuration. In chemical reactions, oxygen atoms form chemical bonds with other elements by sharing or donating electrons to complete their electron shells. What does the term ‘ Valency ’ mean? The valency of an element is a measure of its combining capacity and can be defined as the number of electrons that must be lost or gained by an atom to obtain a stable electron configuration. What does the term ‘Oxidation State’ mean? The oxidation state of an atom is the number of electrons lost or gained by it. Oxidation State and valency are one of the most fundamental properties of elements and can be studied with the help of electron ...
