What Are The Chemical Properties Of Hydrogen Gas?

It is the first element in the periodic table. It is a colorless, odorless and insipid gas in normal conditions, formed by diatomic molecules, H2. The hydrogen atom is formed by a nucleus with one unit of positive charge and one electron. The atomic number of hydrogen is 1 and its atomic weight 1,00797 g/mol. It is one of the main compounds of water. It's widely spread not only in The Earth but also in the entire Universe. It has three hydrogen isotopes: protium, mass 1, found in more than 99,985% of the natural element; deuterium, mass 2, found in nature in 0.015% approximately, and tritium, mass 3, which appears in small quantities in nature. It can be artificially produced by various nuclear reactions.

At normal temperature it is a not very reactive substance, until it has been activated somehow; for instance, by an appropriate catalyser. At high temperatures Hydrogen is highly reactive this gas can be burned in internal combustion engines. Its fuel cells are being looked into as a way to provide power and research is being conducted on hydrogen as a possible major future fuel. For instance Hydrogen can be converted to and from electricity from bio-fuels, from and into natural gas and diesel fuel, theoretically with no emissions of either CO2 or toxic chemicals.
