S2- ion is isoelectronic with argon (with 18 electrons).
Argon is isoelectronic with the sulfide ion.
Sulphur is not iso-electronic with any noble gas. However sulphide ion (S2- ion) is iso-electronic with argon with 18 electrons.
None. The Se2- ion is isoelectronic with Krypton.
The noble gas that is isoelectronic with the oxide ion O2 is neon (Ne). Both the oxide ion O2 and the neon atom have 10 electrons.

The noble gas neon (Ne), is isoelectronic with N3- ion (not N atom)
Oxide ion (O2-) is isoelectronic with neon. Both species have the same number of electrons, which is 10.
None. However, the noble gas helium is isoelectronic with Li+ ion (and not with Li element)
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
Mg2+ and neon are isoelectronic
Chlorine needs only one additional electron to form an ion that is isoelectronic with an atom of the noble gas argon, while sulfur needs two additional electrons to form an ion that is isoelectronic with an atom of the noble gas argon. Ions that are isoelectronic with noble gas atoms are particular stable; therefore, their formation is favored.
Krypton and selenide ion are isoelectronic with 36 electrons each
