chemical symbol.
2. Name 4 other elements not in the first 20 on the periodic table and give their
chemical symbol.
3. Name two elements that have been named after planets.
4. Make a word using element symbols.

6. Which are there less of in the periodic table? Solids, Liquids or Gases.
7. We studied the metals in the first column of the periodic table through
demonstrations and video.
a. Describe the reaction of these metals with water.
b. What happened to the reaction for the metals further down the
column?
8. What is special about the gases in the last column of the periodic table?
9. What did the video show about the gases further down the column?
10. Why did the video not show the next element in the first and last column?

happened.
12. Describe how you could test if a small amount of a gas was hydrogen.
13. Describe how you could test if a small amount of a gas was Oxygen.
14. Describe the apparatus known as Hoffmann’s voltameter. You should include
what it does and how you can make it work.
15. Why was there a difference in the amount of gas in each tube of the
voltameter.
