WebHelium-2 or 2 He is an extremely unstable isotope of helium. Its nucleus, a diproton, consists of two protons with no neutrons. According to theoretical calculations, it would have been much more stable (although still undergoing β + decay to deuterium) if the strong interaction had been 2% greater. [14] kew in focusWebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8. kewill rated supply chain managementWebStep B: 1 proton and 1 deuterium fuse to make a 3 He nucleus (i.e. a nucleus that has 2 protons and 1 neutron) and a gamma ray.
