    B and C

    Explanation:

    A is not true. That is an entirely different atom

    B is possible. The neutrons don't effect the atomic number or the place on the periodic table.

    C is also correct. The nitrogen is just a little heavy.

    D has too few protons. It is not part of the nitrogen family.
