Metals tend to have Low Ionozation Energies. What properties of elements in the metal groups do you think are the result of this tendency

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.

Solubility would be your answer.
