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 to be three, …

: 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.

From the smallest part to a large aerostructure assembly, Valence is your one-stop-shop in the supply chain for metal finishing. Valence is Nadcap, AS9100, and ITAR certified.

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 both the power …

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 …

This capacity is called valence, and it varies periodically with increasing atomic weight. The noble gases all have valences of 0 because they almost never combine with any other element. H and Cl both …

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 …

For a main-group element, a valence electron can exist only in the outermost electron shell; for a transition metal, a valence electron can also be in an inner shell. An atom with a closed shell of …
