    1. The problem statement, all variables and given/known data
    hi
    this is a problem that puzzles me. it goes like this:
    energy/10?18 J
    ionisation level 0.0
    level D
    level C
    level B
    ground state A
    ?1.9
    ?2.1
    ?2.4
    ? 4.6

    An electron with kinetic energy 2.6 × 10?18 J collides inelastically with an electron
    in the ground state.
    State which energy levels may be occupied following this collision.

    A photon of energy 2.6 × 10?18 J is incident on an electron in the ground state.
    State and explain what would happen.



    2. Relevant equations
    e= h1 - h2



    3. The attempt at a solution

    i looked at the kinetic energy needed to escape the ground state. if i calculate 4.6-2.6, i get 2j of kinetic energy. the electron cant get to level d. will b to c be correct?

    for the second part, i am speculating the kinteic energy will have no effect at the ground level. but i am not totally sure. can someone please explain.

    please comment.
