This tutorial is a description of atoms and molecules. It is important to study about atoms even if they are insignificant in size. It is because this entire world where we live is made up of atoms. We may not be able to see them but they exist and constantly affect whatever we do. In this lecture series we will be looking at different kinds of atoms and molecules, their masses and writing their symbols and chemical formulae. We will also be discussing about mole concept towards the end. So, I wish you a happy learning.
These video lectures have been prepared exclusively for the students of class 9 of English Medium Central Board of Secondary Education, who ought to have a better understanding of the “Structure of the atom."
