The periodic table gives us information about element symbols, atomic numbers, and atomic weights. It brings order to information about the chemical elements and helps chemists to understand why elements react as they do.
The milestone in the development of the periodic table was set by the Russian chemist Dmitri Mendeleev in 1869, who is acknowledged as the ‘father’ of the periodic table though the title is also claimed by the German scientist Lothar Meyer. Today, the periodic table organizes the elements by order of increasing atomic number.
