: the combining power of an atom as shown by the number of electrons in its outermost energy level that are lost, gained, or shared in the formation of chemical bonds.

Valence is generally understood to be the number of chemical bonds that each atom of a given chemical element typically forms. Double bonds are considered to be two bonds, triple bonds …

VALENCE definition: the ability of an atom to combine with other atoms, measured by the number of electrons it will…. Learn more.

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 …

Valence bond theory describes bonding as a consequence of the overlap of two separate atomic orbitals on different atoms that creates a region with one pair of electrons shared between the …

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 …

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 …

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 …
