CHEMICAL BONDING
MODULE - 2 Chemistry Atomic Structure and CHEMICAL BONDING 5. Notes CHEMICAL BONDING . I n lesson 1 you have learnt about the structure of atom while in the lesson 2 you studied about the classification of elements and the variation in atomic properties . You know that molecules are obtained by the combination of two or more than two atoms of the same or different elements. In this lesson you will study Why do atoms combine? What are the different ways in which the atoms can combine?, and What are the shapes of different molecules? The answers to these questions are of fundamental importance to the study of chemistry, as you would discover while studying the later parts of this course.
5.2.2 Characteristic Properties of Ionic Compounds These exist as crystalline solids in which the ions are arranged in a regular three dimensional structure. The ionic compounds are generally hard and brittle in nature. These compounds have high melting and boiling points due to strong electrostatic interactions between the ions.
