  1. In lab we studied the Bohr model of the hydrogen atom which is verified exactly with quantum mechanical calculations. From quantum mechanics we also find that Bohr’s equation can be used for any one-electron cation like He+, Li2+, Be3+ etc, by including the atomic number, Z, of the cation in the equation with Bohr’s constant ():
    En= -Z2n2(Accurate for any one-electron cation with atomic number Z)

    1. Use this equation to calculate the energy (J) of the first and second energy levels in a Li2+ cation.

      E1 =



      E2 =


    2. What wavelength of radiation would be emitted when an electron transitions from the n = 2 to the n = 1 level in Li2+?





    3. Thinking question: What energy level in Li2+ would have the same energy as the n = 2 level in a hydrogen atom?
