In this video explains the periodic classification of elements, its need and the historical aspects leading to the development of periodic table. The structure and application of modern periodic table is discussed on the basis of electronic configuration of elements. Some important atomic properties like atomic size, ionization enthalpy, electron gain enthalpy, electro negativity, etc are discussed and correlated to electronic configuration. The periodic trends in physical and chemical porperties are discussed in the light of atomic properties.
