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.

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 …

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 two atoms. …

Valence electron Four covalent bonds. Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent. In chemistry and physics, valence …

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 amount of power of an atom which is determined by the number of electrons the atom will lose, gain, or share when it forms compounds.

Valence electron, electrons in the outer shell of an atom's energy levels Valence quarks, those quarks within a hadron that determine the hadron's quantum numbers
