argon and S2- are isoelectronic
S2- ion is isoelectronic with argon (with 18 electrons).
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Cl & K ions are isoelectronic with Ar.
Sulphur is not iso-electronic with any noble gas. However sulphide ion (S2- ion) is iso-electronic with argon with 18 electrons.

Sulfide ion (S2- ion) (and not sulfur element) is isoelectronic with argon
They have the same electron configuration as argon, which means they are isoelectronic with argon.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Cl & K ions are isoelectronic with Ar.
Sulphur is not iso-electronic with any noble gas. However sulphide ion (S2- ion) is iso-electronic with argon with 18 electrons.
Phosphide is isoelectronic with argon.
Potassium is isoelectronic with the cation K+.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
