  1. 1 Atoms, Ions, and Molecules

  2. Bell Ringer 09.07.11 • Which of the following represents an organic molecule? • A. CuSO4 H2O • B. C12H22O11 • C. AgNO3 • D. H2O

  3. Atom • Smallest basic unit of ______. • What else have we identified as a basic unit of structure and function?

  4. Element • Type of atom • Can’t be broken down into a simpler substance • Identified by number of ______ • How can we identify the number Of protons, neutrons and electrons From this picture?

  5. Elements • Carbon, Oxygen, Nitrogen and Hydrogen =96% of human body’s mass

  6. Bohr Model Draw a hydrogen, oxygen, and carbon atom. Check your book to see how many protons, neutrons, and electrons to include.

  7. Ions and Isotopes • ________-same number of protons (same element) different number of neutrons (different mass) • Ex: Carbon-14 • ________-atom or group of atoms with a positive or negative charge • Ex: Na+ • Is this a cation or anion? What’s the difference?

  8. Compounds • Different elements bonded together in a certain ratio • Can be _______ or ________ • Examples?

  9. Compounds • Compounds often have different ______ than the elements that compose them. • Example: water

  10. Chemical Bonds • Chemical bonds form between ______ • Different types: Ionic and Covalent

  11. Assignment • Create a diagram showing the differences between Ionic and Covalent bonds. • Use your textbook and the article provided for information • Include: • Characteristics • Pictures/Drawings • Examples
