                                           Hydrogen Element Facts

Hydrogen is the first element in the periodic table and has an atomic number of 1. The term has been derived from Greek words ‘hydro’ and ‘genes’ that mean water and forming respectively. Hydrogen makes up about 10 percent of the weight of living organisms most of which is found in water, proteins and fats. It is also the most abundant element in the entire universe. It is also believed to be one of three elements produced in the Big Bang along with helium and lithium.  It reacts explosively with oxygen, chlorine and fluorine.  This element forms both negative and positive ions.

Quick Facts: –

  • Hydrogen has an atomic weight of 1.00794 that makes it the lightest element.
  • It has three natural isotopes which are protium, deuterium and tritium. Protium is the most common among all of them.
  • Hydrogen compounds are commonly known as hydrides.
  • At room temperature and pressure, it is colourless and odourless gas.
  • This gas is highly inflammable and used as a fuel by the space shuttle main engine.
  • The two states, gas and liquid are non-metals so when compressed into a solid, it is known as an alkali metal.
  • It is the only atom for which Schrodinger has an exact solution.
  • It has the molecular formula H2.
  • This element can exist as a liquid under high pressure and extreme low temperatures.
  • It is often prepared by the electrolysis of water.
  • Industrial uses of hydrogen element include production of ammonia and process fossil fuels.
