Valence (chemistry) In chemistry, the valence (US spelling) or valency (British spelling) of an atom is a measure of its combining capacity with other atoms when it forms chemical compounds or …

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 …

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 …

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. A carbon atom, for example, can share four electrons with other atoms and therefore has a valence of 4.
