Which properties are most common in nonmetals

High ionization energies
High electronegativities
Poor thermal conductors
Poor electrical conductors
Brittle solids—not malleable or ductile
Little or no metallic luster
Gain electrons easily
Dull, not metallic-shiny, although they may be colorful
Lower melting points and boiling point than the metals

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.

The answer to this problem is. 67
