Hey Mate! Here's your answer
Mendeleev's Periodic Law (1869):
The first significant classification was given by Mendeleev in the form of periodic table, commonly known as Mendeleev's periodic table. His periodic table was based on periodic law. ''The physical and chemical properties of elements are periodic functions of their weights.''

In Mendeleev's periodic table, elements are arranged in order of their increasing atomic weights in such a way that elements with similar properties are placed in the same group. It consists of seven horizontal rows called periods. These are numbered from 1 to 7.
