16.2b History of Atomic Theory Webquest LINKS
A. Democritus link
1. What year did Democritus propose his atomic theory?
2. What did this theory say?
3. Aristotle added to this theory. What did he add? Was it correct?
4. Why was this theory so much more accepted by the public when his theory was way off?
B. Rutherford
Video- Cathode Ray Tube
This is as a 2 minute video with a real cathode ray tube :)
Video- Cathode Ray Tube & Electrons ----NOT WORKING SKIP!!!!!
5. Describe a cathode ray tube.
C. Thomson link
6. How did Thomson use the cathode ray tube in his research? What particle did he discover?
7. What were 3 properties of electrons that were discovered by experimenting?

14. Thomson's atom model resembled what?
http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/rutherford-model.html
15. What did Rutherford think was going to happen in his experiment, if Thomson’s model was correct?
16.Rutherford’s experiment did not completely turn out like he hypothesized. What happened that he didn’t think would?
17.How did his model differ to Thomson’s?
18.Why was Rutherford’s model called the planetary model?
D. Bohr link
19. Bohr’s model of the atom is also considered a planetary model. What information did he add to Rutherford’s model?
E. Schodinger link
20. How does Schödinger say electrons really move & where?
21. What is this theory called? Include the date of this model
22.Does Schödinger say that we can ever really predict where electrons will be? If not, what does he say is the best we can do?
What do some people say about Schödinger’s cat? Why? Bonus
Summary: 20 Points
On a SEPARATE SHEET of paper and staple to this one.
Draw, label & put into the correct order by date when theory was made.
Include the year made, name of the scientist & common name of the model.
Also include following labels where appropriate: electron, neutron, proton, quark
Plum Pudding Model
Nuclear(Planetary) Model
Bohr’s Model
Electron Cloud Model.
