  1. The model should show 27 protons and 27 neutrons.

    The model should show 27 protons and 32 neutrons.

    The model should show 59 protons and 27 neutrons.

    The model should show 32 protons and 59 neutrons.

  2. From Google:

    While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.
