    1. This question relates to energy levels in the hydrogen atoms.
      1. Calculate the energy change when an electron is promoted from the n = 2 to the n = 9 level in a hydrogen atoms
    1. If the electron falls back from the n = 9 to the n = 2 level, calculate the wavelength of light corresponding to this transition.
    1. If the range of visible light is from 400nm to 750nm, in which region of the electromagnetic spectrum will this emitted light be located?
    1. If the electron in a hydrogen atom is moved from the n = 2 to the n = ∞ (infinity) energy level, why does the associated energy change NOT equal the ionization energy of the hydrogen atom?
