re: #676 abolitionist

If it has fewer neutrons than protons, it’s going to be very unstable —very short half-life. ALL elements are isotopes. The term refers to variations in the number of neutrons, for any particular number of protons.

I think this is the best answer to my question I knew that the protons determine what element the atom was. Didn’t realized thou that basically all real world atoms were Isotope. Always thought there were a few that had an equal number of protons to neutrons.
