Elements are classified for systematic and simplified study of elements and their compounds. The basic property of elements used in the Modern Periodic Table is the atomic number of the elements. Modern Periodic Law states that "the properties of elements are a periodic function of their atomicnumber."
Metals are found on the left side and centre of the Modern PeriodicTable.
Non-metals are found on the right side of the Modern Periodic Table.
Metalloids are found in a zig-zag manner between the metals and the non-metals.
