  1. Today is October 3, 2012 • You need to finish your review sheet from yesterday ON YOUR OWN! • There is no talking for the beginning of class • I’m going to walk around and see what you have done to take a grade so get busy

  2. Give me five properties ofMETALS • Shiny • Good Conductor of heat and electricity • Ductile • Malleable • High Melting point

  3. Give me five properties ofNONMETALS • Dull • Poor Conductor of heat and electricity • Brittle • Low Melting point • Half are gases

  4. Give me two examples of Metalloids and tell me properties of Metalloids: • Metalloids have properties of both metals and nonmetals • Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium, Astatine
