Since this is not my area of expertise, I searched Google under the key words "neutron proton elements isotopes" to get these possible sources:

http://www.mcwdn.org/Physics/Atoms.html
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.
