3. Metals Left side of the periodic table –except H Properties: –lustrous (shiny) –good conductors of heat & electricity –malleable & ductile –solids at RT (except Hg)

4. Non-Metals Right side of table –plus H Properties: –Dull appearance –Brittle when solids –Do not conduct heat or electricity well –May be solid, liquid or gas at RT

5. Metalloids Stair step between metals and non- metals Properties in between metals and non-metals –Si: brittle but semi-conductor

6. Families

7. very reactive metals that do not occur freely in nature softer than most other metals (to the point that they can be cut easily with a knife) can explode if they are exposed to water ALKALI METALS

8. They are harder, denser, and stronger than the alkali metals with higher melting points They are so reactive they are not found as free elements in nature ALKLINE EARTH METALS

9. Metals with typical metallic properties Less reactive than group 1 and 2 metals – some are so unreactive that they exist in nature as free-elements Iron, cobalt, and nickel, are the only elements known to produce a magnetic field. TRANSITION METALS

10. HALOGENS "halogen" means "salt-former" and compounds containing halogens are called "salts" Most reactive non-metals exist in all three states of matter: Solid- Iodine, Astatine Liquid- Bromine Gas- Fluorine, Chlorine

11. NOBLE GASES Nonreactive due to their complete valence shells Do not easily gain or lose valence electrons All gases at room temperature
