If you go backwards two elements, you will find Neon (Ne). If you go forwards six, you will find Argon (Ar).
Ca2+ is isoelectronic with the noble gas, Argon. F-, Mg2+ are isoelectronic with the noble gas, Neon. I- is isoelectronic with the noble gas, Xenon
The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 18 electrons.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
None. However, the noble gas helium is isoelectronic with Li+ ion (and not with Li element)
None. The Se2- ion is isoelectronic with Krypton.
Krypton is the noble gas isoelectronic with calcium, meaning they have the same number of electrons.
Ca2+ is isoelectronic with the noble gas, Argon. F-, Mg2+ are isoelectronic with the noble gas, Neon. I- is isoelectronic with the noble gas, Xenon
The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 18 electrons.
The noble gas neon (Ne), is isoelectronic with N3- ion (not N atom)
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
None. However, the noble gas helium is isoelectronic with Li+ ion (and not with Li element)
None. The Se2- ion is isoelectronic with Krypton.
Neon, Ne.
No noble gas is isoelectronic with the element chlorine. But argon is isoelectronic with the chloride ion.
Magnesium element has no relation with noble gas. But Mg2+ ions and noble gas neon are isoelectronic.
[Rn] 5f6 7s2
Argon is isoelectronic with the sulfide ion.
