WebIn principle, there is an isotope of element 114 that should do even better. The expectation, long before 114 was even produced, was that ununquadium 298 should be particularly stable. The nucleus of this isotope would have 114 protons and 184 neutrons, which should provide complete energy levels in the nucleus and hence unusual stability. WebThe mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus.
