This enables chlorine to fill its outer electron shell with hydrogen's electron, but hydrogen's nucleus (a proton) also comes along for the ride. When hydrogen chloride comes into contact with water (H 2 O) it transfers the proton to the water molecule, which creates two charged molecules (HCl becomes Cl - , and H 2 O becomes H 3 O + ).
The chlorine and carbonic oxide are, it is evident from these last facts, united by strong attractions; and as the properties of the substance as a peculiar compound are well characterized, it will be necessary to designate it by some simple name.
