Notes 9/5 : Fundamentals Thursday, September 7, 2017 8:53 PM Key Terms: • Matter: is anything has mass and/or occupies space • Chemical Changes: changes in chemical properties of a substance (ex. Rusting) • Physical Changes: changes in physical form but not the chemical makeup (ex. melting) • Atoms:basic unit of matter made up of protons neutrons and electrons • Nucleus: Made up of protons (+) and neutrons (no charge) • Orbitals: Ring(s) around the nucleus that hold the electrons (-) Classificationsof Matter: Mixtures Vs. Pure Substances • Can in someway • CANNOT be be separated divided chemically • One single • Heterogeneous: substance Has separate • Ex: sugar components,not the same all the way through • Homogeneous:the same all the way through *In ancient Greece matter was classified into four basic categories: earth, fire, water &air* • The air in our atmosphereis HOMOGENEOUS (the same all the way through). • Most clear substances that you can see through are homogeneous. Subatomic Particles: 1. Electrons Negative Charge (-) Revolve around the nucleus in orbitals 2. Protons: PositiveCharge (+) Inside nucleus 3. Neutrons No Charge (0) Inside nucleus Elemental Properties: Atomic #= is the # of protons found in t
