Modern Periodic Table is the tabular arrangement of the elements in increasing order of their atomic numbers. It is commonly referred to as the Long Form of the Periodic Table and is based on the modern periodic law and is the tabular arrangement of elements in increasing order of their atomic numbers (Z).
*Numbering system adopted by the International Union of Pure and Applied Chemistry (IUPAC).
The periodic table of elements is as follows:
