Introduction
Classification of Elements and Periodicity in Properties is an
important chapter of Class 11 Chemistry that explains the basis of
arranging elements in the periodic table. This chapter introduces modern
periodic law and discusses periodic trends such as atomic radius, ionisation
energy, electron gain enthalpy, and electronegativity.
A clear understanding of periodic trends is essential for CBSE Board
examinations and for solving conceptual questions in NEET and
JEE (Main).
