  1. What Are We Doing Today? • Collect Assignment 1 • Quiz (find a place away from everyone) • Recycling • Explain APES classes • What is the Difference between: Lewis, Ball & Stick, Bohr Rutherford, Simplified • Isotopes (notes & video) • Metals & Non-Metals Lab

  2. Quiz • Make sure to sit away from anyone else • You need a pencil or pen • Close your books & notes • Make sure you put your name on the quiz • When you are finished, put your hand up and I will come and collect your quiz.

  3. Recycling Jobs How did they go? Any problems?

  4. APES (explained)

  5. Atomic Models…(What is the difference) • Ball & Stick • Lewis Structure • Rutherford-Bohr • Simplified

  6. Ball & Stick Model Draw the ball & stick model for Carbon

  7. Lewis Structure Draw the Lewis model for Carbon

  8. Rutherford-Bohr Model Draw the Ruth-Bohr model for Carbon

  9. Simplified Model p.28 Draw the Simplified model for Carbon

  10. ISOTOPES. What are they? They are different versions of an atom. Isotopes are atoms which have the same atomic number but different mass numbers. They have the same number of protons but different numbers of neutrons.

  11. The number of neutrons in an atom can vary within small limits. For example, there are three kinds of carbon atom 12C, 13C and 14C. They all have the same number of protons, but the number of neutrons varies.
