  1. PSAE Chemistry Review The study of matter and energy

  2. PSAE Chemistry Review • Matter • Anything with mass and volume • Energy • Ability to cause change or do work

  3. PSAE Chemistry Review • The atom • Basic unit of matter • Made of smaller particles • Electrons orbit the nucleus due to electrostatic charges

  4. PSAE Chemistry Review • Three Subatomic Particles

  5. PSAE Chemistry Review • Element • A pure sample of matter containing only one type of atom • Compound • More than one type of atom chemically bonded together • Mixture • More than one type of atom in the same space but not bonded together

  6. PSAE Chemistry Review • Physical change • Change in state without changing the chemical formula. • Always involves absorbing or emitting energy • Solid  Liquid  Gas  Plasma • Chemical Change • A change in the chemical formula of a compound • Changes the properties of the chemicals involved • 2 KI (aq) + Pb(NO3)2 (aq)  2 KNO3 (aq) + PbI2 (s)

  7. PSAE Chemistry Review • Periodic Table of the Elements
