The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 18 electrons.
None. The Se2- ion is isoelectronic with Krypton.
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.
Argon is isoelectronic with the sulfide ion.
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)
None. The Se2- ion is isoelectronic with Krypton.
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.
Argon is isoelectronic with the sulfide ion.
Helium does not have chemical properties similar to Br (bromine). Helium is a noble gas and is chemically inert, while bromine is a reactive nonmetal.
Neon, Ne.
The symbol for the most stable ion of bromine is Br-, which is the bromide ion. Bromine typically forms anions by gaining one electron to achieve a stable electron configuration similar to a noble gas.
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 the oxide ion O2 is neon (Ne). Both the oxide ion O2 and the neon atom have 10 electrons.
