Chemistry is about understanding the properties of different substances and how these substances can change. Chemistry allows us to predict how substances may alter when the surrounding conditions change, or how they may react to form new substances, and to explain why this happens. Chemists are continually changing matter into new and more useful forms.
Chemical transformations happen all the time, everywhere. Chemistry goes on continuously, all around us; in plants that make food using the air and in animals that digest this food, in the burning of fuel and rusting of cars, in the formation of snow and ice, in the industries that supply us with all our household products, and in the many biological processes that maintain the living world.
Chemists interpret the world from an atomic perspective. Chemists and students who study chemistry use their understanding of atoms, molecules, and ions – particles that are too tiny to be seen with our eyes – to explain and predict the properties and behaviour of different materials.
