  1. Basic Chemistry www.assignmentpoint.com

  2. Matter Matter = any material substance with Mass & Volume www.assignmentpoint.com

  3. Solid Gas Liquid Matter comes in 3 phases www.assignmentpoint.com

  4. Solid Definite Shape Definite Volume www.assignmentpoint.com

  5. Liquid Indefinite Shape – takes the shape of the container Definite Volume www.assignmentpoint.com

  6. Gas Indefinite Shape – takes the shape of the container Indefinite Volume – can expand and be compressed www.assignmentpoint.com

  7. Elements one of the 100+ pure substances that make up everything in the universe www.assignmentpoint.com

  8. H = Hydrogen Na = Sodium Ca = Calcium C = Carbon K = Potassium O = Oxygen I = Iodine N = Nitrogen Cl = Chlorine S = Sulfur P = Phosphorus Examples of Elements www.assignmentpoint.com

  9. Atom the smallest particle making up elements www.assignmentpoint.com

  10. Sub-atomic Particles Protons p+ - positive charge, in nucleus Neutrons n0 – no charge, in nucleus Electrons - e- negative charge, orbiting nucleus www.assignmentpoint.com

  11. 6 Atomic # C 12.011 Atomic Mass Drawing an Atom of Carbon = # of p+ and # of e- Carbon has 6 p+ and 6 e- minus Atomic # = # of n0 Carbon has 6 n0 www.assignmentpoint.com

  12. e- e- 6 p+ 6 n0 e- e- e- e- Drawing an Atom of Carbon www.assignmentpoint.com

  13. Compounds Compounds - 2 or more elements chemically combined to form a new substance with new properties Properties– The way a chemical substance looks and behaves www.assignmentpoint.com

  14. H + O H2O = O H H Compounds Compounds – are made of 2 or more different atoms combined to form Molecules Chemical formula lists the number of different atoms in a single molecule Structural formula shows the arrangement of the atoms in a single molecule www.assignmentpoint.com

  15. H H C C O C6H12O6 H H H C C H O H O H O H O H C C Chemical formula H O H Structural formula Molecules Glucose Sugar www.assignmentpoint.com

  16. Inorganic Compounds Organic Compounds or Compounds • usually don’t contain Carbon • generally come from the earth • generally simple molecules • always contain C & H and usually O, N, sometimes S & P • originate in organisms • generally complex molecules www.assignmentpoint.com

  17. H + O = H2O = Water H + Cl = HCl = Hydrochloric Acid C + O = CO2 = Carbon Dioxide Na + Cl = NaCl = Common Table Salt Examples of Inorganic Compounds www.assignmentpoint.com

  18. Carbohydrates = Sugars, starches & cellulose C, H + O C, H + O Lipids = Fats & Oils C, H, O, N, & sometimes P + S Proteins C, H, O, N, + P Nucleic Acids – DNA & RNA Examples of Organic Compounds www.assignmentpoint.com
