Chemistry Honors – Classes 29 & 30

Dates
- Period B: Tuesday, March 10th & Wednesday, March 11th
- period D: Tuesday, March 10th & Thursday, March 12th
- Period G: Wednesday, March 11th & Thursday, March 12th
Recap of Activity
- what did we see with spectrum tubes?
- what was same about each? different?
- this was evidence that changed science > 100 years ago
New Idea – Quantum Mechanics
- How to explain lines? QUANTIZATION
- light emitted when transitioning between levels
- LINES = discrete levels
- SAME LINES = same levels for each element
- DIFFERENT LINES = different levels for each element
- Level Number = principal quantum number
- Smart people figured out how to predict light
Light Energy and Wavelength
Activity
- create the light spectrum for Hydrogen
- H-spectrum
- RESULT = drawing the line spectrum of Hydrogen
- you will submit this on PAPER with appropriate supporting work
- Note – you only need to show one example of each type of calculation
- Note – this is NOT A LAB REPORT
