The diagram represents energy levels in a hydrogen atom. The labeled transitions (A through E) represent an electron moving between energy levels.
 
  Suppose that an electron in a hydrogen atom absorbs 10.2 eV of energy, so that it moves from level 1 to level 2. What typically happens next?
  A) The electron remains in level 2 until it absorbs an additional 10.2 eV of energy.
  B) The electron jumps to level 3 as soon as it absorbs any additional energy.
  C) A different electron drops into level 1, since it is now unoccupied.
  D) The electron returns to level 1 by emitting an ultraviolet photon with 10.2 eV of energy.
