Top 19 interesting facts about Sodium

  • Sodium's symbol is Na which comes from the Latin word Natrium.
  • Sodium was discovered in 1807 by Sir Humphrey Davy.
  • Sodium is a soft metal, silver to white color, and very reactive.
  • 23Na is its only stable isotope.
  • Being so reactive, elemental Sodium can not be found freely in nature but obtained from its compounds.
  • Sodium is the sixth more abundant element in the Earth crust.
  • Sodium is a dietary inorganic macro-mineral because all animals (and some plants) need it.
  • At standard temperature Sodium is very soft and can be cut with a knife.
  • Sodium is a very good conductor of electricity.
  • When Sodium takes contact with fire it changes its color in yellow because the electrons start emitting photons.
  • Reactively, Sodium stays somewhere between Potassium and Lithium.
  • Obtaining Sodium from its compounds requires great amount of energy.
  • Sodium has 20 isotopes but only one is stable.
  • As many other elements, Sodium is created in big stars (at least three times bigger than our Sun) by the fusion of two atoms of Carbon.
  • Sodium compounds are vastly used in glass, paper, soap, and textile industries.
  • Sodium is produce by the electrolysis of sodium chloride.
  • Sodium is very difficult to be stored and transported due to its high reactivity.
  • Blood pressure, blood volume, and PH in human body is regulated by Sodium.
  • Sodium's melting point is at 97.794 °C (370.944 K, 208.029 °F) and boiling point at 882.940 °C (1621.292 °F, 1156.090 K).
