No, it has a single covalent bond with the two electrons allowing each atom to attain the helium configuration. If "CO" was written as the chemical symbol for cobalt, it would be the same as the chemical formula for carbon monoxide. Atoms that have been excited by an electric discharge, emit light when an electron drops from a high-energy orbit (such as n = 6) into a lower energy orbit (such as n = 1). aaa123456789100. theMar_J.
