[...] dos clases de átomos de helio:3He y4He, que se distinguen por la naturaleza de sus núcleos. El núcleo de3He contiene dos protones y un neutrón; el de4He, dos protones y dos neutrones. Ambos núcleos poseen, pues, el mismo número de protones, lo que indica que presentarán la misma carga eléctrica.
