Ca2+ is one of them
This is because the mass number of Argon (which is 18) lost 2 electrons (which has a negative charge). Without the impedance of the negative charge, Argon's mass number becomes 20 (instead of 18) and it acts like Calcium (which has the mass number of 20).
You can probably figure out the rest of them from the above.

If calcium lost two electrons it would have the same number of electrons as?
Argon
Number of electrons in argon?
In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
Which would have the same number of electrons as s2-?
S2- ie sulphide ion has 18 electrons(16+2) another specie which has same number of electrons is Cl-(17+1) and Argon(18 electrons)
Which noble gas atom has the same number electrons as a sulfide ion?
This noble gas is argon (Ar).
What does isolelectronic mean?
having equal electronic chargeAnswer-2The ions of different elements having the same number of electrons are called as isoelectronic ions as F-, O2-, Na+, Mg2+ and Al3+.
Is argon the only element with 18 electrons?
Yes. Argon is the only neutral element with 18 electrons. However, there can be other ions that can be isoelectronic (having same number of electrons) with argon. Cations such as K+, Ca2+ or Sc3+ have 18 electrons. Anions such as Cl-, S2- or P3- have 18 electrons.
Which noble gas has the same number of electrons as an ion of barium?
There is no such noble gas with the same electron configuration as helium ion. Helium is the first noble gas, is stable and does not form ions. There can be, however, other ions such as H- or Li+ that will have the same number of electrons as element helium.
A chloride ion has the same number of electrons as a neutral atom of?
argon
What ions have the same number of electrons as a noble gas out of Aluminum oxygen bromine and nitrogen?
Actually all the ions will have. Al3+, O2- and N3- ions will have the same number of electrons as neon (10 electrons), whereas Br- ion will have the same number of electrons as krypton (36 electrons)
Which element has same electron as argon?
The element that has the same number of electrons as argon is Krypton (Kr). Both argon (Ar) and krypton (Kr) have 18 electrons in their neutral state.
If calcium lost two electrons it would have the same number of electrons as?
Argon
Does Ca2 have the same number of electrons as the noble gas argon?
Yes. The ion Ca2+ and the element argon, have 18 electrons each.
Number of electrons in argon?
In any neutral atom, the number of electrons is the same as the number of protons, and that is defined as the atomic number of the atom. The atomic number of argon is 18; therefore, each atom contains 18 electrons.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
What pair what has the same number of valence electrons magnesium and potassium lithium and calcium argon and xenon phosphorus and tellurium?
Argon and Xenon have the same number of valence electrons, both are noble gases (group 18 that have 8 electrons).
A chloride ion (Cl-) has the same number of electrons as a neutral atom of -?
argon
A chloride ion has the same number of electrons as a neutral atom of what element?
