We wrote about the Periodic table here and you can check that article out before you continue with this one. The physicochemical properties of an element depend on the electron configuration of its atom. According to the periodic law, the outer electron configuration of atoms recurs periodically hence any property of the
The Periodic table represents a simple systematic way of classifying elements. A Russian Scientist Mendeleev 1869 formulated the periodic law based on the relative atomic mass of the elements however, the modern version which is currently in use today is based on their atomic numbers and it was suggested by Moseley in
