They have the same electron configuration as argon, which means they are isoelectronic with argon.
They all have the same electron configuration as the noble gas argon.
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
is electronic all have electronic config of {Ar} size Ca^2+^<k+<Cl-<s2-< IE S2-<CL-<K+<CA2+
calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]
Yes, it is identical to Ar.

Not exactly as asked in the question. But K+, Ca2+ and Ar all have the same electronic configuration. All will have a total of 18 electrons.
Cl-, K+, Ca2+ all have [Ar] configuration with 18 electrons (1s2, 2s2 2p6, 3s2 3p6)
( a + ar ) = a ( 1 + r )
(Ar) Argon because Ca ion is Ca2+ so it give away 2 electrons
It forms a divalent cation, Ca2+, by losing two electrons and attains the electronic configuration of [Ar].
