In covalency
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent o… Webnoun co· va· lence ˌkō-ˈvā-lən (t)s ˈkō-ˌvā- : valence characterized by the sharing of electrons Word History First Known Use 1919, in the meaning defined above Time Traveler The first …
