lacked intelligence
had understanding of scientific principles
had understanding of mathematics
required millions of years to evolve
developed technologies which somehow were lost

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.
