WebIntramolecular Bonds. Intramolecular bonds are the bonds that hold atoms to atoms and make compounds. There are 3 types of intramolecular bonds: covalent, ionic, and metallic. Covalent Bond: a bond in which a pair or pairs of electrons is shared by two atoms. Molecular compounds refer to covalently-bonded species, generally of low molecular mass.
