Need to understand this to help improve and develop the world. Understanding the small parts of the world will help you understand the larger parts. Atom: indivisible matter; can not break down. The smallest unit that keeps all properties. E- electrons: outer electron cloud (determines properties of element) Has a compound nucleus of protons and neutrons. Completely mixed together; dissolved completely or blended smoothly. Do not mix together, both are present. A mixture of sand and water can be separated by decanting. Mixtures are separable because the different components have different physical or chemical properties. A mixture of an insoluble solid and a liquid can be separated by filtration- process in which the mixture is poured through a filter paper in a funnel.
