HYDROGEN

INTRODUCION
First element in the periodic table. In normal conditions it’s a colorless, odorless and insipid gas, formed by diatomic molecules, H2. The hydrogen atom, symbol H, is formed by a nucleus with one unit of positive charge and one electron. Its atomic number is 1 and its atomic mass is 1.00794. It’s one of the main compounds of water and of all organic matter, and it’s widely spread not only in The Earth but also in the entire Universe. There are 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, but can be artificially produced by various nuclear reactions. Hydrogen is used to process fossil fuels and is used to produce ammonia which is used in common household cleaning products. Hydrogen is often a compound with oxygen to create water, an element in ammonia, methane, table sugar, hydrogen peroxide, and hydrochloric acid. Molecular hydrogen can react with many elements and compounds, but at room temperature the reaction rates are usually so low as to be negligible. This apparent inertness is in part related to the very high dissociation energy of the molecule. At elevated temperatures, however, the reaction rates are high. It often reacts quickly oxygen to create water most often.
