Homework Help: Energy Levels

  1. Dec 4, 2009 #1
    1. The problem statement, all variables and given/known data
    The graph below shows all of the quantized energies (bound states) for one of these molecules. For this molecule, E0 = -2.5 eV, E1 = -1.20 eV, E2 = -0.72 eV, and E3 = -0.30 eV. What is the minimum amount of energy required to break a molecule apart, if it is initially in the ground state? (Note that the final state must be an unbound state; the unbound states are not quantized.)

    2. Relevant equations

    Dont think i need any

    3. The attempt at a solution

    I honestly dont know what to do any help will be helpful

    What does it mean that the ground state energy is negative 2.5 eV?
