  1. Nonmetals

  2. Nonmetals in Periodic Table

  3. Examples of NONMETALS Non metals may be solids, liquids or gases. Examples: Solids – Carbon, Sulfur, Phosphorus Liquid – Bromine Gases – Oxygen, Hydrogen, Nitrogen

  4. Physical Properties of NONMETALS Nonmetals have a dull luster. (They are not shiny!) Example: Phosphorus

  5. Physical Properties of NONMETALS Nonmetals are insulators. They do not conduct electricity or heatwell. The atoms in nonmetals do not have loose electrons. Therefore, when electricity, or something hot touches a non-metal, the energy does not move quickly through the material. What would you rather stir a hot pot with—a wooden spoon or a metal spoon?

  6. Physical Properties of NONMETALS Nonmetals aresoft(except for diamonds and brittle. Example: Sulfur

  7. Physical Properties of NONMETALS Some nonmetals maybe different in color. Example: Phosphorus

  8. An interesting element: Carbon Ever break the point of your pencil? That’s because it’s made of graphite, a substance made up completely of Carbon—a brittle nonmetal. Carbon atoms in graphite However diamonds, the hardest material of all, are made of the same element: Carbon. Look at how the carbon atoms are arranged in diamonds.

  9. To nonmetals include inert (noble)gases Each molecule of the inert (noble) gas consists of one atom

  10. Thank you for your attention!
