We all know that there are 118 elements present in our periodic table. Out of these 118 elements, 94 elements are natural elements and 24 elements are synthetic elements. Back in the year 1800, only 30 elements were known. With the discovery of more and more elements, remembering the elements and their properties were burdensome for scientists. They started gathering information about the elements and categorizing it. The categorization of elements in a tabular form according to their properties became popular. The tabular form structure in which various elements are arranged according to their properties is known as the periodic table. Dmitri Ivanovich Mendeléev, a Russian chemist, was the most important contributor to the early development of the periodic table. Many periodic tables were made but the most important one was Mendeleev periodic table.
