Define Periodic Table and how many elements are there in a periodic table known to us.

Answered by admin @ 10/08/2021

The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson. The atomic number of an element is the number of protons in the nucleus of an atom of that element.

Since 2016, the periodic table has 118 confirmed elements, from element 1 (hydrogen) to 118 (oganesson).
