Either open a new file or print out a copy to answer the following questions while watching the [Annenberg Learner Chemistry Challenges and Solution, Unit 4 Organizing Atoms and Electrons: The Periodic Table.](30min long)

You will need to go down to the embedded video and click on the expand it to full screen to watch the video. While watching the video answer the questions below.

1. Originally, were there more than one type of Periodic Table? (Yes or No)

2. Who is called the Father of Periodic Table? (don't worry if get spelling incorrect, phonetic out)

3. What does each row (or Period) indicate?

4. What are similar with elements that are in the same Group/column?

5. How does the size of the element (in Row 4 and Row 5) change as you go across row? Reactivity?

6. How did Moseley arrange elements in his Periodic Table?

7. What information is in each block of Periodic Table?


8. What is Reactivity?


9. What is Reactivity of element related to (two words)?

10. Electrons are located outside the nucleus in what?

11. When atom reacts, which elements will interact and what are they called? 12. Why does Sodium valence electron tend to be removed from the atom when it reacts?

13. Why doe the elements in the Alkali metal Group all look similar to other elements reacting with it? What does this do?

14. How many electrons (we call valence) do every element want to have in their valence shell (highest energy level)?

15. Using the Periodic Table helps in determining the valence electrons. All elements in the same row (Period) of the Periodic Table have the same what with respect to their valence electron?

16. What does Group/column on Periodic Table show us about Valence shell?

17. What are the different block of Periodic Table? And where are each located on Periodic Table?

18. Who changed the bottom of the Periodic Table?
