So, the title. As far as I understood, tritium is radioactive because it has more neutrons that protons and one neutron that’s not being held by a proton is slowly decaying through beta decay. Oxygen 18 has 10 neutrons and 8 protons, but it’s not radioactive at all. Why?
In: Physics
It’s not that the number of neutrons are higher than protons, it’s that those specific number of neutrons can’t easily be held together by those specific number of protons.
