What stable ion sulfur should form based on its electron configuration?
The stable ion the sulfur would form is the sulfide ion,
A neutral sulfur atom contains 16 electrons. We can know this because its atomic number is 16, which means there are 16 protons in the nucleus. Since the negative charge of the electrons cancels the charge of the protons, the sulfur atom is neutral. The electron configuration of sulfur is
The following video shows how magnesium sulfide is formed, in which the magnesium atom donates its two valence electrons to a sulfur atom, forming a magnesium 2+ ion and a sulfide 2- ion, which are attracted to each other in an ionic bond.
