electron-pair bond
21sigma bond — ▪ chemistry in chemistry, a mechanism by which two atoms are held together as the result of the forces operating between them and a pair of electrons regarded as shared by them. In a sigma bond, the electron pair occupies an orbital a… …
22single bond — noun a covalent bond in which one electron pair is shared between two atoms See Also: double bond, triple bond …
23Metallic bond — Metallic bonding is the electrostatic attractive forces between the delocalized electrons, called conduction electrons, gathered in an electron sea , and the positively charged metal ions. Understood as the sharing of free electrons among a… …
24Coordinate covalent bond — [ ammonium ion] A coordinate covalent bond (formerly also known as dative bond [GoldBookRef | file = D01523 | title = dative bond] ) is a description of covalent bonding between two atoms in which both electrons shared in the bond come from the… …
25Hydrogen bond — A hydrogen bond results from a dipole dipole force between an electronegative atom and a hydrogen atom bonded to nitrogen, oxygen or fluorine (thus the name hydrogen bond , which must not be confused with a covalent bond to hydrogen). The energy… …
26Pi bond — In chemistry, pi bonds (π bonds) are covalent chemical bonds where two lobes of one involved electron orbital overlap two lobes of the other involved electron orbital. Only one of the orbital s nodal planes passes through both of the involved… …
27Metal ligand multiple bond — In Chemistry, ametal ligand multiple bond describes the interaction of certain ligands with a metal with a bond order greater than one. [ Metal Ligand Multiple Bonds: The Chemistry of Transition Metal Complexes Containing Oxo, Nitrido, Imido,… …
28Metal–ligand multiple bond — In Chemistry, a metal–ligand multiple bond describes the interaction of certain ligands with a metal with a bond order greater than one.[1] Coordination complexes featuring multiply bonded ligands are of both scholarly and practical interest.… …
29Carbon-nitrogen bond — A carbon nitrogen bond is a covalent bond between carbon and nitrogen and one of the most abundant in organic chemistry and biochemistry [ Organic Chemistry John McMurry 2nd Ed.] .Nitrogen has five valence electrons and in simple amines it is… …
30Inert pair effect — The term inert pair effect is often used in relation to the increasing stability of oxidation states that are 2 less than the group valency for the heavier elements of groups 13, 14, 15 and 16. The term inert pair was first proposed by Sidgwick… …
