argon and S2- are isoelectronic
The noble gas that has the same electron configuration as sulfur with a 2- charge (S²⁻) is argon. When sulfur gains two electrons to become S²⁻, its electron configuration becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is identical to that of argon. Thus, both sulfur 2 minus and argon have the same electron arrangement, making them isoelectronic.
Yes, S^2- is isoelectronic with Ar (argon) since both have 18 electrons and the same electron configuration.
[Ne] 3s2 3p4
[He] 2s2 2p2 (the 2's to the right of each letter mean squared)
Be3+ has only 2 valence electron and not 8.

no S is not a noble gas inorder to become a noble gas u need to have a completely filled outermost shell

Noble gases
P 3- is the ion with the noble gas configuration.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
Cl & K ions are isoelectronic with Ar.
The nearest noble gas with an atomic number lower than sulfur (S) is neon (Ne) with an atomic number of 10.
