Sodium | Chemical elements

Sodium’s symbol is Na which comes from the Latin word Natrium. It was discovered in 1807 by Sir Humphrey Davy.

Top 17 interesting facts about Sodium

  1. Sodium is a soft metal, silver to white color, and very reactive.
  2. Na-23 is its only stable isotope.
  3. Being so reactive, elemental Sodium can not be found freely in nature but obtained from its compounds.
  4. Sodium is the sixth more abundant element in the Earth crust.
  5. Sodium is a dietary inorganic macro-mineral because all animals (and some plants) need it.
  6. At standard temperature Sodium is very soft and can be cut with a knife.
  7. Sodium is a very good conductor of electricity.
  8. When Sodium takes contact with fire it changes its color in yellow because the electrons start emitting photons.
  9. Reactively, Sodium stays somewhere between Potassium and Lithium.
  10. Obtaining Sodium from its compounds requires great amount of energy.
  11. Sodium has 20 isotopes but only one is stable.
  12. 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.
  13. Sodium compounds are vastly used in glass, paper, soap, and textile industries.
  14. Sodium is produce by the electrolysis of sodium chloride.
  15. Sodium is very difficult to be stored and transported due to its high reactivity.
  16. Blood pressure, blood volume, and PH in human body is regulated by Sodium.
  17. 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).
