Chlorine ions - gain an electron to be - 1s2, 2s2, 2p6, 3s2, 3p6 same electronic configuration as Ar
Ca, Ne
An (mono atomic) ion is called isoelectronic with another element (or ion) when it has the same number of electrons with it. (they are in the same period or it is the preceeding noble gas).Examples:Na+ and Mg2+ are both isoelectronic with Ne (element) and with each other. Even Al3+ is isoelectronic with them all: They are all surrounded with 10 electrons, hence they have the same 'noble gas' configuration.S2- and Cl- are isoelectronic with Ar (and with eacht other): all with 18 electrons around.
Phosphide is isoelectronic with argon.
Potassium is isoelectronic with the cation K+.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
Methyl carbocation (CH3+) is isoelectronic with borane (BH3).
Argon (Ar)
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Cl & K ions are isoelectronic with 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
They have the same electron configuration as argon, which means they are isoelectronic with argon.

(Ar) Argon because Ca ion is Ca2+ so it give away 2 electrons
Phosphide is isoelectronic with argon.
Potassium is isoelectronic with the cation K+.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
O3 is the allotrope of oxygen that is isoelectronic.
