Physical Properties of Matter
A chemist can view things at the macroscopic and microscopic level. The macroscopic level includes anything seen with the naked eye. The microscopic level includes atoms and molecules, things not seen with the naked eye. Both levels describe matter. Matter is anything that occupies space and has mass. However, light is not matter. It is a form of energy. Matter can be in three states: Solid, Liquid, or Gas.
