Hydrogen is the most common element in the universe. Approximately 10% of the entire weight of living organisms is made up of hydrogen. It has the atomic number 1 and chemical symbol ‘H’. It makes more than 65% of the elemental mass of the universe. Melting point of hydrogen is -259.14°C and boiling point is -252.87°C. This gas has three isotopes that occur naturally: – protium, deuterium and tritium.

Facts you didn’t know: –

  • In 1783, Antoine Lavoisier gave the name hydrogen to this gas. This word is derived from the Greek word where ‘hydro’ means water and ‘genes’ means forming.
  • Hydrogen is a tasteless, colourless and odourless gas.
  • It is the third most common element on the earth’s surface.
  • As this gas is very light in weight so it easily escapes the earth’s gravity as compared to other heavier gases.
  • A hydrocarbon is a compound that contains carbon and hydrogen both. There are millions of known hydrocarbons.
  • Hydrogen is very abundant in stars like the Sun and gas giants like planet Jupiter.
  • It is the only element that can exist without neutrons.
  • Three elements are believed to be produced in the Big Bang: – Hydrogen, Helium and Lithium.
  • Schrödinger equation has an exact solution for only one atom that is hydrogen.
  • Hydrogen can easily bond with other non-metals. Compounds of hydrogen are called hydrides.
  • The atomic weight of hydrogen is 1.00794.
  • Two hydrogen atoms (H2) bond with one single atom of oxygen (O) and form the most essential things for living organisms, water (H2O).
