19+ Periodic Table Trivia Questions and Answers

Dmitri Mendeleev, a Russian chemist, created the framework for the modern periodic table in 1869, leaving gaps for elements yet to be discovered. Today, we refer to this as “Mendeleev’s periodic table.” Many people regard the modern periodic table as something they must memorize as part of their chemistry class or when there’s a chemistry quiz, but the truth is that this small table is an indispensable guide for scientists all over the world. 

There were several blank spaces in Mendeleev’s original periodic table when he assembled it with the known elements. Mendeleyev was able to correctly predict the discovery of the new elements by estimating their properties relative to other elements near the spaces on the table.

Periodic Table Trivia

How much do you know about the Periodic Table? Do you know the symbol of every element? How many interesting facts about the periodic elements do you know?

  • The number of protons in an atom is called atomic number and isotopes have the same atomic number but differ in the number of neutrons. 
  • The total weight of an atom is called the atomic weight.
  • Technetium is the very first man-made element, and it was synthesized in 1937. However, it is found naturally in very small amounts in tiny traces.
  • Oxygen is the most abundant element in the world, making up around 46% of the total mass of the earth.
  • Pure elements are those elements whose atoms all or nearly share the same atomic number or number of protons. 
  • Earlier chemical symbols come from classical Latin and Greek vocabulary. For some elements, this is because the material has been known since antiquity, whereas for the rest of the group, the name is a more modern invention.
  • The first set of atomic symbols was devised by John Dalton.
