CBSE Class 11 Chemistry Chapter 3 - Periodicity in Properties and Classification of Elements

Brief Information: In this chapter, you will learn about a brief history of the periodic table and its development, the significance of classifying periodic table, how the present form of the periodic table was formed, etc. Furthermore, the information about the trends in the periodic table for atoms like ionic radii, radii, inert gas radii, electronegativity, electron gain, valency, etc. is more discussed in this chapter.

Topics Covered

• Modern periodic law and the present form of periodic table
• Periodic trends in properties of elements -atomic radii, ionic radii, inert gas radii, Ionization enthalpy, electron gain enthalpy, electronegativity, valency
• Nomenclature of elements with atomic number greater than 100.
