Russian chemist, Dimitri Mendeleev, was the inventor of the periodic table that depicts 150 different chemicals and physical properties. To the surprise of most individuals, the famous periodic table that we routinely reference may have looked entirely different. A good example of how it could have looked is Heinrich Baumhauer’s chemical spiral that he invented in the year of 1870. The final format of the periodic table wasn’t even taken on until the 20th century.

Key Takeaways:

  • The UN has declared 2019 to be the year of the periodic table to celebrate the 150th anniversary of Mendeleev’s painstakingly writing out the periodic table.
  • Before Mendeleev did this and became successful, John Dalton tried to write out a table for the elements along with some symbols for them but it was not as popular.
  • Mendeleev’s genius that distinguished him from other periodic table creators, was what he left out in his table – he allowed for the existence of then undiscovered elements.

“But the periodic table didn’t actually start with Mendeleev. Many had tinkered with arranging the elements.”
