Easy Rutherford Question

  1. Apr 24, 2008 #1
    X-rays striking a piece of gold foil may cause:

    a. electrons to be emitted
    b. isotopes of gold to form
    c. addition of protons to gold atoms
    d. addition of neutrons to gold atoms
    e. nuclear transmutation of gold into another element

    I think the answer is a or c. Can someone help me? Thanks.

    Consider that C and E are saying basically the same thing; if gold obtained another proton, it would become another element because elements are defined by the number of protons they have.
