Chemistry is the scientific discipline that investigates the properties, composition, structure, and transformations of matter. It is a fundamental branch of science that explores the interactions between atoms, molecules, and various substances, as well as the energy changes that occur during these interactions. Chemistry plays a crucial role in understanding the world around us, from the composition of the air we breathe to the complex reactions happening within our bodies. In this IGCSE Chemistry course, you will learn about the atom, how chemical reactions occur at the quantum scale, how energy is transferred during chemical reactions, and finally, learn about the most up-to-date field in chemisty, organic chemistry.
