Presentation Transcript

  1. Bell Ringer • List the 4 properties of metals. • What are the properties of metalloids? Nonmetals? • Based on their location on the periodic table define each of the following elements as metal, nonmetal, or metalloid AND predict some of the properties you would expect to observe. (Make a chart!) • Aluminum, Carbon,Copper, Magnesium, Silicon, Sulfur, & Zinc ***This is to be turned in tomorrow with your LAB!

  2. Metal, Nonmetal, or Metalliod Lab Prep

  3. Classes and Selected Groups of the Periodic Table • Metals • Alkali Metals • Alkaline Earth Metals • Transition Metals • Metalloids • Non - Metals • Halogens • Noble Gases

  4. Metals • Solidat room temperature • Malleableand ductile(can change shape) • Malleable = compress without breaking • Ductile = stretch without breaking • Good Conductors(thermal & electrical) • Luster(means they are shiny!)

  5. Metalloids • Share characteristics of both metals & non – metals. • Semi – conductors

  6. Nonmetals • Insulators (poor conductivity) • Living organisms are mostly non-metals. (especially C, N, O, P, S) • Most of the compounds in your body contain carbon

  7. Aluminum

  8. Carbon

  9. Copper

  10. Magnesium

  11. Silicon

  12. Sulfur

  13. Zinc

  14. SAFETY!!! • Hydrochloric acid solution (HCl) is corrosive to eyes and skin. • Cupric chloride solution (CuCl2) is toxic if ingested. • Avoid contact of all chemicals with eyes and all body tissues. • Wearchemical splash gogglesand thoroughly wash hands after the experiment.

  15. Observe & Record • Color • Luster • Other physical properties: rough, smooth, rocky, flaky, flat, etc. • Malleable or brittle • DO NOT TOUCH with Hands! • Conductivity **** Record in table – BE SPECIFIC

  16. Chemical Properties • Observe reaction with HCl • Observe reaction with CuCl2

  17. Disposal • Using spatula or forceps, carefully remove the silicon samples and place them in the designated container. • For all other samples, dump the contents of the spot plates into the designated container – the instructor will dispose of these later. • Rinse out the spot plates and spatula/forceps with water, and dry them off with paper towels.
