1. Classification of Matter 2. Physical vs. Chemical Properties 3. States of Matter The Heart of the Matter

Pure Substances Made of one type of matter Elements Made of one type of atom Compounds Made of 2 or More atoms bonded together Homogeneous one phase MATTER Made of Atoms Has Mass & takes up Space Heterogeneous Made of more than one phase Can be separated Mixtures Made of more than one type of matter Solute The stuff that is dissolved In the liquid Ex: Kool-Aid mix Atom + Atom = diatomic Molecule Molecule + Molecule = Compound Atom + Atom = Molecule Solution All its regions are Identical Ex: Kool-Aid Solvent The liquid that forms the solution Ex: Water Examples: Trail Mix Salad Classification of Matter + Molecule + Molecule = Element
