Facts About the Periodic Table

The Periodic table is a tabular representation of chemical elements ordered by their atomic number, electron configuration, and recurring chemical properties. Elements in the periodic table are unique and according to scientists, it is not possible to break these elements down into any smaller units. Here are some facts about the periodic table.

  • In the periodic table, elements are represented in the form of Chemical Symbol, the Atomic Number, and the Atomic mass.
  • The periodic table has 109 different elements.
  • Among the 109 elements, 90 of them are found in nature.
  • Out of these 109 elements, 19 are created in the laboratory.
  • Russian scientist Dmitri Ivanovich Mendeleev formulated and invented the periodic table.
  • Carbon is one of the unique element which is known to form up to 10 million different compounds.
  • J is the only alphabet which is not in the periodic table.
  • Argentina is named after the element silver (Ag) which is Argentum in Latin.
  • The first artificially made element is Technetium.
  • Most of the elements present in the periodic table are metals.
  • The present periodic table has space for 118 elements.
  • The main difference between the Mendeleev’s periodic table and the modern periodic table is that the modern periodic table orders the element in increasing atomic number and the Mendeleev’s periodic table order the elements in order of increasing atomic weight.
  • The organization responsible for maintaining the periodic table is The International Union of Pure Applied Chemistry (IUPAC).
  • Mercury and bromine are the two elements which are liquid at room temperature.
  • Hydrogen, being the lightest with an atomic weight of 1 and uranium being the heaviest element in the periodic table with an atomic weight of 238.
  • Do you know? Why is the table called the periodic table? It is because the rows are called the periods.
  • Helium was first discovered in sun despite it is the second most abundant element in the universe.
  • By the start of the 19th century, more than 50 elements were discovered by the scientists.
  • When argon was discovered, it did not fit in Mendeleev’s columns, so Mendeleyev’s denied the existence of argon.
