  1. States of matter; solids Metals vs. nonmetals

  2. Which elements are metals? Metals are on the left side of the periodic table

  3. Solids at room temp. except Mercury Shiny “metallic” High Density Properties of METALS Malleable Ductile Conductor of electricity Conductor of heat

  4. Periodic Table All the elements shaded in yellow have those metallic properties.

  5. Some common uses of metals are in sprinkler-systems. (Bismuth) in roadflares; the red color. (Strontium) in medicine; absorbs harmful x-rays & gamma rays (Barium)

  6. Periodic Table The elements in Group 1 are the absolute best of all metals! They are called ALKALIMETALS

  7. Which elements are NONMETALS? Nonmetals are on the right side of the periodic table

  8. Mostly gases at room temp. Dull; not shiny Low Density Properties of NONMETALS Brittle; not malleable Non- conductors

  9. Periodic Table All the elements shaded in blue have those nonmetallic properties.

  10. Some common uses of nonmetals are in dandruffshampoos (Selenium) in toothpaste (Fluorine) in rayon (Sulfur)

  11. Periodic Table The elements in Group17 are the absolute best of all nonmetals! (or the worst of all metals!) Group 17 elements are called HALOGENS

  12. What about the green elements? These are called METALLOIDS.

  13. They are the transition elements between metals and nonmetals Some are shiny (aluminum) Some are dull (arsenic) Properties of METALLOIDS Most are considered semi-conductors

  14. Some common uses of metalloids are in aerospace (strong but light) (Boron) in infrareddetectors (Germanium) in ratpoisoning (Arsenic)

  15. Periodic Table periodic table Pick one element that interests you; metal or nonmetal! You are going to adopt an element andl do a research project about it
