Tag: Nature and Behaviour of Matter

Materials in all forms, i.e. solids, liquids and gases are all made up of matter. All matter is made up of atoms. Atoms are made up of three types  particles, the protons, neutrons and electrons. Matter can exist as elements, mixtures and compounds. Materials can be classified as metals or non-metals. Some metals are more reactive than others. Some materials are acids bases or salts. Speeds of reaction are affected by temperature, concentration, surface area and the presence of catalysts.
