User can create, shape and manipulate hydrogen, a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas, the lightest of all gases and the most abundant element in the universe, that occurs as the diatomic molecule 2. Since hydrogen readily forms covalent compounds with most non-metallic elements, most of the hydrogen on Earth exists in molecular forms such as in the form of water or organic compounds.
