1. Rank the items from the highest change in energy to the lowest change in energy. To rank items as equivalent, overlap them.
- n=2 to n=5
- n=1 to n=3
- n=1 to n=5
- n=3 to n=4
2. An electron undergoes a transition from an initial (ni) to a final (nl) energy state. The energies of the and energy states are -2.179 X 10^-18 J and -8.720 X 10^-20 J respectively.
Calculate the wavelength of the light in nanometers corresponding to this transition. You can use the following values for your calculations:
