  1. Classifying Matter

  2. MATTER • Matter – anything that has mass – anything that has volume • Mass - quantity of matter contained in an object • Volume – amount of space occupied by an object • Weight – the force of attraction between matter and earth Person… on Moon… on Earth… Mass same same Weight 1/6 x W lbs. W lbs. Gravity 1/6 G G

  3. Elements Matter Impure Substances Compounds Mixtures PURE SUBSTANCES

  4. Elements Compounds Mixtures Matter Monoatomic Element • Elements whose atoms travel alone • Na, He, Fe, U Diatomic Element • Elements whose atoms always are paired • H2, O2, N2, Cl2, Br2, I2, F2 Elements are composed of one type of atom.

  5. Elements Matter Compounds Mixtures 2 or more DIFFERENT Elements combined chemically • NaCl • H2O • NaHCO3

  6. Elements Matter Compounds Mixtures 2 or more DIFFERENT Elements or Compounds combined physically • NaCl & H2O • Fe & KCl

  7. Elements Matter Compounds Mixtures Heterogeneous Mixture that is not the same throughout Homogeneous Mixture that is the same throughout Solutions • Salt water • Kool-Aid • Alloys Suspension • Salad Dressing Colloid • Milk • Tyndall effect

  8. Tyndall effect is easily seen using a laser pointer aimed at the the mist from this ultrasonic humidifier's mist

  9. Colloid Solution

  10. Colloid Solution Colloid

  11. Identify the classification of matter Homogeneous mixture/ Solution Heterogeneous mixture/ Suspension Compound
