In some older formulations of Lewis structures, a distinction was made between bonds formed by electrons that have been supplied by both atoms (as in HCl, where one shared electron can be regarded as supplied by the hydrogen atom and the other by the chlorine atom) and covalent bonds formed when both electrons can be regarded as supplied by one atom, as in the formation of OH from O2 and H+.
