F.Sc. 2nd year Chemistry Chapter 1 notes

This chapter “Periodic Classification of Elements and Periodicity” is about the classification of elements and their properties. The elements are arranged in the form of a table called periodic table. The periodic table provides a basic framework to study the periodic behaviour of physical and chemical properties of elements as well as their compounds.
In modern periodic table all the elements are arranged in ascending order of their atomic numbers.

  • There are eight groups which are usually numbered by Roman numerals I to VIII.
  • There are seven periods in the periodic table numbered by Arabic numerals 1 to 7.

The major concepts of chapter no. 1: Periodic Classification of Elements and Periodicity is given below
