  15. Topic 3 – 30 Points QUESTION: • The _________ wave equation said that electrons exist in regions called orbitals. ANSWER: • Schrodinger

  16. Topic 3 – 40 Points QUESTION: • What was wrong with Bohr’s model? ANSWER: • electrons couldn’t switch energy levels, and the electrons don’t travel in perfect circular paths

  17. Topic 3 – 50 Points QUESTION: • Explain the Heisenberg uncertainty principle. ANSWER: • states that it is impossible to determine simultaneously both the position and velocity of an electron or any other particle Daily Double

  18. Topic 4 – 10 Points QUESTION: How many arrows does an atom of Silicon have in its orbital notation? ANSWER: • 14

  28. Final Jeopardy Question: When I put zinc nitrate into a flame, a bright red flame is produced. What is happening to the zinc’s electrons and what does that specific color tell us about the energy, wavelength and frequency of the light wave? Answer: The electrons are jumping energy levels and releasing red light wave photons as they fall back to ground state. Big wavelengths, low frequency, low energy.
