The periodic table of elements developed as scientists tried to classify elements. It arranges them in an order in which similar elements are grouped together. The periodic table is so named because of the regularly repeating patterns in the properties of elements. The modern periodic table was formed by a Russian scientist called Mendeleev in ...
