3.1.1 Identify that matter is made of particles that are continuously moving and interacting The particle theory states that all matter is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds

Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection
