- Calculate [delta]E, frequency, and wavelength for the following transitions in the hydrogen spectrum.
- Lyman [alpha] line n=1 to n=2
- Balmer line n=2 to n=4
- Ionization of H n=1 to n=[infinity]

- Compare the three different types of radioactive particles. What are the differences between these particles?
- Based upon the wavelength information given in figure 7.3, calculate the typical energy in J mol
^{-1}for gamma rays, X- rays, and Radio Waves. - I just bought a new truck, calculate the DeBroglie wavelength if it is traveling down the highway at 65 miles per hour (the truck has a weight of 3675 pounds). Calculate the DeBroglie wavelength for an electron (mass 9.10953 x 10
^{-31}kg) traveling at a speed of 100,000 miles per hour. Compare the wavelengths and their relative significance. - Sketch the shape of the s, p
_{x}, p_{y}, and p_{z}orbitals.
