The change on sulfur in sulfide ion is -2 and it has the same electronic configuration as the noble gas argon
The sulfide ion (S²⁻) obtains its charge by gaining two electrons. Sulfur, which has six valence electrons, tends to gain two additional electrons to achieve a stable electron configuration similar to that of the noble gas argon. This gain of electrons results in a net negative charge of -2, leading to the formation of the sulfide ion.
Atoms that are close to achieving a noble gas configuration through the gain or loss of a few electrons are most likely to share electrons to achieve a noble gas configuration. These are usually atoms in groups 14-17 of the periodic table, such as carbon, nitrogen, oxygen, and fluorine. They form covalent bonds through electron sharing to achieve stability.
A sulfide ion will have a charge of -2. This is because sulfur is in Group 6 of the periodic table and typically forms ions by gaining two electrons to achieve a stable, noble gas electron configuration.
The noble gas nearest to Phosphorus (P) is Argon (Ar).
Sulfide, S2-
Sulfide typically has an ionic charge of -2. This is because sulfur, the element in sulfide, usually gains two electrons to achieve a stable electron configuration similar to a noble gas.

Sulfur, which has six valence electrons, tends to gain two additional electrons to achieve a stable electron configuration similar to that of the noble gas argon. This gain of electrons results in a net negative charge of -2, leading to the formation of the sulfide ion.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
When sulfur gains electrons, it forms the sulfide ion with a 2- charge, represented as S2-. When sulfur loses electrons, it forms the sulfide ion with a 2+ charge, represented as S2+.
Argon (Ar) is the nearest noble gas to potassium.
An atom of sulfur-36 can gain two electrons to become a sulfide ion with a -2 charge. When it gains these two electrons, it achieves a stable electron configuration, similar to the noble gas configuration of argon, resulting in a charge of -2.
Chromium III is Cr3+. The roman numeral tells you the charge. Sulfide is S2-. You can figure this out from the periodic table. Sulfur needs two electrons to be like Argon, the next noble gas. When they form a compound, they combine in a ratio such that the total positive charge balances the total negative charge. 2 Cr3+ ions have a total charge of +6. 3 S2- ions have a total charge of -6. So the formula is Cr2S3.
Krypton (Kr) has the same number of electrons as a sulfide ion. Both have 36 electrons.
