In step two of Experiment 4, you add sodium hydroxide to copper(II) nitrate and use a stirring rod to test if the solution is basic. How do you establish whether the solution is basic

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.
