Two scientists were working on an idea. They kept in touch by asking each other questions about which designs worked better . After months of experiments one of the scientists discovered a breakthrough. He tested it several more times and got the same result.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
