1. CHEM-TO-GO LESSON 7: ENERGY OF ELECTRONS CONVERSATION STARTER Materials: 1)Energy of Electrons video notes 2)Unit 2 Practice Packet 3)Pencil and calculator

2. Collaborative Analysis Experience Students will apply knowledge to a real-world situation. Any questions about the Atomic Mass Calculations Practice? ADVICE:  #2 doesn’t require any math.  #5 is really tough! I will help you with it if you can’t figure it out. FROM YESTERDAY…

3. Calculators Look for any of the following buttons on your calculator. (They may be 2 nd functions.)  EE  EXP  x10 n Use these buttons to enter scientific notation into your calculator. NOTE: I know that many of you believe that the ^ button works, but it is inconsistent with our calculations. You’ll only get about 50% correct.

4. Useful to know how much energy is coming out of an atom Useful to know how much energy to put into an atom to achieve a particular color Useful to calculate the energy c = λν c = 3.0x10 8 m/s E = hν h= 6.626x10 -34 J·s

5. Collaborative Analysis Experience Students will adapt knowledge to an unpredictable situation. Flame Test Experiments and the Electromagnetic Spectrum As we watch the video, let’s: 1)Estimate the wavelength of the light based on its color 2)Calculate the frequency of the light 3)Calculate the energy of the light

6. Collaborative Analysis Experience Students will apply knowledge to a real-world situation.

7. Collaborative Analysis Experience Students will apply knowledge to a real-world situation. Let’s learn how fireworks are made.

8. Collaborative Analysis Experience Solve the “Practice Problems: Wavelength, Frequency, Energy Content of One Quantum of Light” questions (1-7, #4 disappeared).
