Information about Hydrogen atom (H)

Hydrogen is the lightest element and its monatomic form (H) is the most abundant chemical substance, constituting roughly 75% of the Universe's baryonic mass. Non-remnant stars are mainly composed of hydrogen in its plasma state.

Henry Cavendish 1731 – 1810 was a British natural philosopher, scientist, and an important experimental and theoretical chemist and physicist. Cavendish discovered hydrogen or what he called "inflammable air".

State Of Matter (At standard temperature): GasMelting point: 259.1 oC, 434.38 oF, 14.05 KBoiling point: 252.879 oC, 423.182 oF, 20.271 K Appearance: A colourless, odourless gas that burns and can form an explosive mixture with air. It is currently manufactured from methane gas, but is also produced by the electrolysis of water and aqueous salts.

Isotopes:Hydrogen has three naturally occurring isotopes, denoted 1H, 2H and 3H. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature.Hydrogen is the only element that has different names for its isotopes in common use today. During the early study of radioactivity, various heavy radioactive isotopes were given their own names, but such names are no longer used, except for deuterium and tritium.

Reactivity:Reaction with air: H2+O2 =>2H2OWhen two molecules of hydrogen are reacted with an oxygen molecule (at standard temperature), we have 2 water molecules.Reaction with oxides: H2+CuO=>Cu+H2O(Heat)Only the element of metal oxides behind magnesium in the periodic table, was reacted with hydrogen.Reation with chlorine: H2+Cl2=>2HClWhen a hydrogen molecule are reacted with a chlorine molecule (at standard temperature), we have 2 hydrochloric acid molecules.Reation with nitrogen: 3H2+N2=>2NH3(ammonia)

Applications in the life:-Loaded into balloons.-Fuel production.-A reduction of the oxygen of the metal oxide.-Hydrochloric acid production.-Ammonia production.
