12/5/11 12/5/11 Presentation Transcript

  • 12/5 A/B DayLEQ: What characteristics distinguishmetals, nonmetals, and metalloids?1. What is the difference between ions and isotopes?2. What is reactivity?3. What is the difference between an element and acompound?4. Why can we eat salt, even though it’s made of twopoisonous elements?5. COPY AND COMPLETE: Stable, or unreactiveelements [do/do not] form compounds.
  • Announcements:NEXT CLASS: QUIZ on ions,isotopes, compounds, reactivity,and today’s lesson(We will review beforehand!!!)
  • Today’s LEQ: What characteristics distinguish metals, nonmetals, and metalloids?By the end of today, you should be able to…1. Identify materials that are malleable, ductile, conductors, and insulators.2. Observe a specific material to determine whether it is classified as a metal, a nonmetal, or a metalloid3. Predict properties of elements by looking at the periodic table
