Answering by example: Cl- ion, Ar atom, K+ and Ca2+ ions are all 'iso-electronic' to each other, because they all have the same 20 electrons in the same (noble gas) electron configuration (structure) as argon has:
[Ar] = [1s2, 2s2 2p6, 3s2 3p6]
The Sulfide ion, S2-, is isoelectronic with Cl-
No, bromine forms an ion with a charge of -1. An ion isoelectronic with krypton would have the same number of electrons as krypton, which is 36 electrons.
The molecular structure of Na2PO3F consists of a sodium ion (Na+) bonded to another sodium ion (Na+), a phosphorus atom (P), an oxygen atom (O), and a fluorine atom (F). The phosphorus atom is bonded to three oxygen atoms (O) and one fluorine atom (F) in a tetrahedral arrangement.
Atoms or ions that have the same number of electrons as helium (2 electrons) are considered isoelectronic with helium. Examples of species that are isoelectronic with helium include H+, Li+, Be2+, and B3+.
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
Neon is isoelectronic with the sodium ion.
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)
Argon is isoelectronic with the sulfide ion.
Oxide ion (O2-) is isoelectronic with neon. Both species have the same number of electrons, which is 10.
S2- ion is isoelectronic with argon (with 18 electrons).
Krypton and selenide ion are isoelectronic with 36 electrons each
None. The Se2- ion is isoelectronic with Krypton.
An atom is isoelectronic with another if they have the same number of electrons. The neutral atom that is isoelectronic with F (9 electrons) is Ne (neon). For Ca²⁺ (20 electrons), the isoelectronic atom is Ar (argon). P³⁻ (18 electrons) is isoelectronic with Ar as well, while K⁺ (18 electrons) is also isoelectronic with Ar. Pb²⁺ (78 electrons) is isoelectronic with the neutral atom Xe (xenon).
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
Yes, sodium ion (Na+), magnesium ion (Mg2+), and aluminum ion (Al3+) are isoelectronic species because they all have 10 electrons. Neon (Ne) is isoelectronic with the other ions as well, having 10 electrons. However, nitrogen ion (N3-) is not isoelectronic with the rest, as it has 10 electrons while the others have 11.
The Sulfide ion, S2-, is isoelectronic with Cl-
