  1. Basics of the Periodic Table

  2. Entrance Slip: 1/28/19 1. On the images below label the following: -Mass Number -Atomic Mass -Atomic Number -Isotope Symbol 2. What happens after an electron changes to a higher energy quantum number? 3. What are the properties of electromagnetic radiation?

  3. Objective: I can explain the key properties of a periodic table Which includes: -Period -Group -Nonmetal -Metal -Metalloid -Key groups

  4. How is the periodic table organized? -Discuss with your groups -Identify characteristics that may be used to organize the elements

  5. How was the periodic table created? 1) Organized by Atomic Mass Are there any exceptions to this on the periodic table?

  6. How is it actually organized? -Atomic Number, from lowest to highest

  7. Cross Off: 6 squares

  8. Period -The PT term for row -7 total rows

  9. 2. Group -PT term for column -18 total -A and B

  10. Group B -Transition Elements -Groups 3-12

  11. 3. Metals

  12. Metals -Good conductors of heat and electricity -Luster -All solid at room temperature but mercury -ductile -Malleable

  13. 4. Nonmetals

  14. Nonmetals -Most are gases at room temperature -Minus: Phosphorus, Sulfur, and Bromine (ssl) -All but Carbon are poor conductors

  15. Add the staircase

  16. 5. Metalloids

  17. Metalloids -Characteristics of both -Depends on changing conditions -Ex Silicon is not a good conductor, if you add Boron then it is

  18. Review Practice What is the name of the element that is in the 13th group, 2nd period? What is the name of the element that is in the 4B group, 7th period?

  19. What groups do we need to know? -Halogen -Noble Gases -Alkali Metals -Alkaline (earth) metals

  20. Research then create a whiteboard/poster paper with: -Where to find it -Key characteristics -Elements we may know that are in this group -How to remember it

  21. Alkali Metal

  22. Alkaline Earth Metals

  23. Halogen

  24. Noble gases

  25. Spectrum Analysis Glasses Questions Pencil Spot where you can see it

  26. Review of Objectives: I can explain the key properties of a periodic table Which includes: -Period -Group -Nonmetal -Metal -Metalloid -Key groups

  27. Exit Slip: -Identify the alkali metal that is in the 4th row -Identify the element that is group 8A, row 6
