  4. 4. SCIENTIST DIVIDE ALL ELEMENTS INTO THREE SECTIONS
  5. 5. METALS SOLID AT ROOM TEMPERATURE  Except mercury HAVE A SILVER-GRAY COLOR  Except gold and copper GOOD CONDUCTORS OF HEAT AND ELECTRICITY HAVE A METALLIC LUSTER MALLEABLE
  6. 6. NONMETALS FOUND IN ALL STATES OF MATTER COME IN MANY COLORS POOR CONDUCTORS OF HEAT AND ELECTRICITY (INSULATORS) NO METALLIC LUSTER NOT MALLEABLE SOME HAVE STRONG ODORS
  7. 7. METALLOIDS HAVE PROPERTIES OF BOTH METALS AND NONMETALS SOME ARE CALLED SEMICONDUCTORS
