Bonding

Chemical bond

Association of atoms to form chemical compounds

Covalent bond

Chemical bond that involves the sharing of electron pairs between atoms

Double bond

Chemical bond involving four bonding electrons; has one sigma plus one pi bond

Electron counting

Formalism used for classifying compounds and for explaining or predicting electronic structure and bonding

Hydrogen bond

Intermolecular attraction between a hydrogen donor-and-acceptor pair

Ionic bonding

Chemical bonding involving attraction between ions

Metallic bonding

Type of chemical bond in metals

Octet rule

Chemical rule of thumblets

Polyatomic ion

Molecular chemical ion

Single bond

Chemical bond between two atoms involving two valence electrons (atoms share one pair of electrons where the bond forms, therefore, a single bond is a type of covalent bond); usually a sigma bond

Triple bond

Chemical bond involving six bonding electrons; one sigma plus two pi bonds
