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 …

The valence is determined by the number of electrons that an atom can lose, add, or share. An atom's valence is positive if its own electrons are used in forming the bond, or negative if another atom's …

While the concepts and definitions of valence have been refined over the years, that described by Sidgwick remains the most useful and simple definition for covalent molecules: the valence of an …

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 …

Jan 14, 2016 · The valence of an atom is the ability of that atom, expressed in numbers, to combine or interact with another atom, depending on the number of electrons available for bonding in the atom’s …

Dec 25, 2025 · A valence diagram of methane showing that one carbon atom can combine with a maximum of four hydrogen atoms, or that it makes four electrons available to form covalent chemical …

the quality that determines the number of atoms or groups with which any single atom or group will unite chemically. b. the relative combining capacity of an atom or group compared with that of the standard …

In chemistry, valence, also known as valency or valence number, is the number of valence bonds a given atom has formed, or can form, with one or more other atoms.

Valence is a fundamental concept in chemistry that describes the combining capacity of an atom. It refers to the number of electrons in the outermost shell of an atom that are available for forming …
