AP Chemistry – Class 32
New Material – Quantum Mechanics
- Spectrum Lines – what do you see in the tubes?
- What is different about each tube?
- What explanation is offered for this?
Activity – Hydrogen Spectrum (use your LNB)
- Calculate the energy of each of the first 7 levels of the hydrogen atom. You will need the Rydberg formula (p. 214) to do this step.
- List all of the possible transitions between these levels, from upper to lower levels. For example: 7-1, 7-2.
- Determine the energy of each possible transition. This is determined by calculating the difference between each transition
- Calculate the wavelength associated with each transition. (Note – see p. 215 for more on this)
- Draw the spectrum for Hydrogen. Draw a line for each wavelength, as if drawing on an axis with the wavelength as “x” axis, and each line drawn to the same length.
- Compare your drawn spectrum to the known spectrum
- Finish spectrum activity
