This is an overview of what topics we are going to cover in this course. Please watch this lesson before starting to watch the lessons.

Course Overview

This lesson covers the definition of matter, its physical properties, the process of diffusion, different states of matter i.e. solid, liquid and gas.

Matter in Our Surroundings - Definition, Properties and States of Matter

This lesson deals with the different process by which a matter can change its state e.g. melting, boiling, sublimation etc. It also deals with the process of evaporation and various factors affecting evaporation.

Matter in Our Surroundings - Change in States of Matter

This is the first part of lessons on "Is matter around us pure". This lesson talks about the notion of pure matter, classification of matter, mixtures and it's classification, solution and it's properties, alloys and it also explain to calculate the concentration of a solution.

Is Matter Around Us Pure? - Classification of Matter and Mixtures

This is the second part of lessons on "Is matter around us pure". This lesson deals with the suspension, colloid and their properties. It also introduces the Tyndall effect. Then it deals with the pure  substances i.e. elements and compounds. It also presents a detailed comparison of compounds and mixtures.

Is Matter Around Us Pure - Suspension, Colloid, Elements and Compounds

This lesson deals with the different techniques to separate out the components of a mixture. It deals with the process of centrifugation and it's application. It also deals with separation of two immiscible liquids and the  separation by using sublimation.

Separation of Components of Mixture - Centrifugation, Sublimation and Immiscible Liquids

This lesson deals with the separation of components of a mixture. It deals with the process of chromatography and it's applications, distillation, fractional distillation and it's applications, crystalization and it's applications.

Separation of Components of Mixture - Chromatography, Distillation, Crystallization

This is a first part of lessons on Atoms and Molecules. This lesson deals with the historical background of the atom, Laws of Chemical Combination and Dalton's Atomic Theory.

Atoms and Molecules - Laws of Chemical Combination and Dalton's Atomic Theory

This is the second part of lessons on Atoms and Molecules which deals with the three important species of matter Atoms, Molecules and Ions. It also deals with Symbolic representation of Atoms, atomicity, and Atomic mass.

Atoms and Molecules - Definition, Symbols of Atoms and Atomic Mass

This is the third and last part of the lessons on Atoms and Molecules. After watching this lesson the learners would be able to write chemical formula of any chemical compound, calculate the molecular mass and formula unit mass. This lesson also throws light on the basic introduction to the Mole Concept.

Atoms and Molecules - Chemical Formula, Molecular Mass and Mole Concept

This is the first part of lessons on Structure of the Atom. It starts with the fundamental question about divisibility of an atom and then deals with the sub-atomic particles i.e. electrons and  protons. It then discuss the Thomson's Model of an atom.

Structure of the Atom - Electrons, Protons and Thomson's Model of Atom

This is the second part of the lessons on Structure of the Atom. It continues with the different models of an atom and deals with Rutherford's Nuclear Model and Bohr's Model of Atom. It also introduces you to Neutrons.

Structure of the Atom - Rutherford's Model and Bohr's Model of Atom, Neutrons

This lesson explains the distribution of electrons in various orbits, valency and the various methods to achieve the octet, isotopes and isobars.

Structure of the Atom - Electronic Configuration, Valency, Isotopes and Isobars
