Answer:
Sulfur (S) typically forms a 2- ion in an ionic compound. The charge on the sulfur ion is negative. When sulfur forms an ionic compound, it gains two electrons and becomes an ion with a 2- charge. This means that it gains two electrons to achieve a stable electron configuration.
The reason for this can be explained using the concepts of electronegativity and the octet rule. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Sulfur has a relatively high electronegativity, meaning that it has a strong tendency to attract electrons.
The octet rule states that atoms tend to gain, lose or share electrons in order to have eight electrons in their outermost shell, achieving a stable electron configuration similar to that of the noble gases. Sulfur has six valence electrons, so by gaining two more electrons, it can achieve a stable octet configuration.
