    http://web.jjay.cuny.edu/~acarpi/NSC/3-atoms.htm
    http://en.wikipedia.org/wiki/Isotope

    After reading the information in these sites, you should be able to answer your own question. In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

    I hope this helps. Thanks for asking.
