  1. Using the Periodic Table 47 Ag 108 19 K 39 Atomic # ____ Mass # ____ # p+ ____ # n ____ # e- ____ Atomic # ____ Mass # ____ # p+ ____ # n ____ # e- ____ 10 Na 20 Atomic # ____ Mass # ____ # p+ ____ # n ____ # e- ____

  2. Atoms What element is this? How can you tell?

  3. Atoms • Valence electrons • electrons in the outer most shell • the electrons that react with other elements • stable, unreactive element has 8 valence electrons (Noble gases) • Bonding • Ionic • Exchange electrons • Metal + nonmetal • Covalent • Share electrons • Nonmetal + nonmetal

  4. Ionic Bonding

  5. Covalent Bonding

  6. pH Scale Weak Base Strong Base High OH- ions Strong Acid Weak Acid High H+ ions neutral

  7. Dehydration Synthesis Glucose + Glucose Sucrose

  8. Phospholipid

  9. Steroids

  10. Proteins

  11. Primary Structure a.a. chains ex: glyc-ser-glu-phe-leu-asn Secondary Structure 3D shape showing H+ bonds beta sheet or alpha helix Tertiary Structure 3D shape showing R group interaction Quaternary Structure 2+ peptide chains linked globularly ex: Hb

  12. Hemoglobin(Transports O2 throughout circulatory system)

  13. Nucleic Acids

  14. Nitrogenous Bases RNA only DNA only
