A Lewis structure will usually require one or more multiple bonds if there is an atom present that does not have a full after all available electrons have already been placed. The multiple bond is formed by exchanging one electron pair for each new bond.

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.

Ibelieve the answer is d. titaniumhope my answer has you : )
