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 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 …

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 …

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

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 …

Jan 20, 2026 · 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 …

Sep 30, 2018 · Valence, or Valency, describes how easily an atom or radical can combine with other chemical species.

May 25, 2014 · The oxidation state tells how many valence electrons an atom accepts (negative number) or donates (positive number) to form a chemical bond. A lithium atom has one outer shell …

: 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.

Jan 24, 2019 · Valence is typically the number of electrons needed to fill the outermost shell of an atom. Because exceptions exist, the more general definition of valence is the number of electrons with …
