  1. number on left is atomic number.
    number on right is mass number.
    11Na24 ==> -1e0 + 12Mg24
    You give no data to determine the remaining part of the question.

  2. In high N divided by Z nuclei, neutrons decay into a proton with the release of a beta particle (beta emissions). The atomic number increases by 1, but mass remains the same

    therefore,

    11Na24 ==> -1e0 + 12Mg24
