S2- ion is isoelectronic with argon (with 18 electrons).
oxide ion is isoelectronic with neon.
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.
Oxide ion O2- is isoelectronic with neon.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
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.
oxide ion is isoelectronic with neon.
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.
The noble gas neon (Ne), is isoelectronic with N3- ion (not N atom)
Oxide ion O2- is isoelectronic with neon.
