The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
In carbon tetrachloride (b), C is connected to four Cl atoms and is tetravalent. In chemistry , polyvalency (or polyvalence , multivalency ) is the property of molecules and larger species, such as antibodies , medical drugs, and even nanoparticles surface-functionalized with ligands, like spherical nucleic acids , that exhibit more than one ...
Monovalence or Monovalent may refer to: Monovalent ion, an atom, ion, or chemical group with a valency of one, which thus can form one covalent bond; Monovalent vaccine, a vaccine directed at only one pathogen; Monovalent antibody, an antibody with affinity for one epitope, antigen, or strain of microorganism
Valence bond theory views bonds as weakly coupled orbitals (small overlap). Valence bond theory is typically easier to employ in ground state molecules. The core orbitals and electrons remain essentially unchanged during the formation of bonds. σ bond between two atoms: localization of electron density Two p-orbitals forming a π-bond.
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 electrons are electrons in the outermost shell of an atom, and that can participate in the formation of a chemical bond if the outermost shell is not closed.
The bond valence method or mean method (or bond valence sum) (not to be mistaken for the valence bond theory in quantum chemistry) is a popular method in coordination chemistry to estimate the oxidation states of atoms. It is derived from the bond valence model, which is a simple yet robust model for validating chemical structures with ...

Iodine itself contains 7 valence electrons, and, in a monovalent iodane such as iodobenzene (C 6 H 5 I), the phenyl ligand donates one additional electron to give a completed octet. In a λ 3 ‑iodane , each X-type ligand donates an additional electron, for 10 in total; the result is a decet structure.
