  1. Fun with the Periodic Table

  2. Task One: Organizing a Store • Clipart from Clipartheaven.com

  3. Essential ? And GPS • How and why do you organize items in everyday life? • SC4 Students will use the organization of the periodic table to predict properties of elements.

  4. What do you see?

  5. What do you think? • How many items does a supermarket have?

  6. What does a Supermarket have to do with the Periodic Table? • You have probably developed categories for many things in your life. What are some examples you can come up with? • Imagine life unsorted without categories. • Think about what a supermarket would be like. • Like items in a supermarket, the elements share similar chemical and physical properties.

  7. Activity 2: Elements and their Properties www.chem4kids.com

  8. Essential ? And GPS • What are the specific properties of materials that allow them to be classified as metals and nonmetals? • SC4. Students will use the organization of the Periodic Table to predict properties of elements. • b. Compare and contrast trends in the chemical and physical properties of elements and their placement on the Periodic Table.

  9. What Do You See?

  10. Directions • 1. Observations: color, appearance, state • 2. Conductivity with probe, light = positive • 3. Add small amount to test tube, add 4-5 drops of HCl to cover, observe chemical changes • 4. Magnetic, put magnet on the bottom of the container and observe • 5. Oxides: Use dropper bottles (share), color change on pH paper

  11. What is an element? • A substance that cannot be broken down or decomposed into simpler substances by chemical means. www.chem4kids.com

  12. Elements

  13. Physical property of a substance is a characteristic that the substance displays and can be measured without undergoing a change in composition. Chemical Property of a substance is a characteristic that the substance displays as it undergoes a change in composition.

  14. Elements and their Properties • Every element has different properties that you will learn about in this activity. • Reactivity with HCl (hydrochloric acid) • Magnetic or Not? • Metal or Nonmetal? • pH of oxide • There are many groups or families of elements • Alkali Metals: they react explosively and are softer than you would think a metal would be •  Alkali Metals: Include Calcium found in your bones and teeth • Transition metals are shiny and they conduct electricity • Metalloids are semi-conductors used in all computer chips • Non-metals include oxygen, nitrogen, and carbon groups • Halogens include fluorine that you have in toothpaste • Noble gases include neon (used in lights), and helium (used in balloons)

  15. Dimitri Mendeleev • Mendeleev is credited with arranging the 63 known elements into a Periodic Table based on atomic mass, which he published in Principles of Chemistry in 1869.

  19. Groups or Families are arranged Vertically

  20. Periods go across the table horizontally
