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.
What else can I help you with?
What ions has isoelectronic with argon?
Isodoetic ions with argon are K+, Cl-, Ca2+, and Sc3+, as they all have the same number of electrons as argon.
If calcium lost two electrons it would have the same number of electrons as?
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same 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-?
Argon (Ar) would have the same number of electrons as S2-. Argon has 18 electrons, while S2- has 18 electrons as well, after gaining two electrons to achieve a full octet like noble gas configuration.
Neutral atoms of argon atomic number 18 have the same number of electrons as each of the following items except?
Neutral atoms of argon (atomic number 18) have 18 electrons. Consequently, they do not have the same number of electrons as hydrogen (1 electron), helium (2 electrons), or lithium (3 electrons).
What ions has isoelectronic with argon?
Isodoetic ions with argon are K+, Cl-, Ca2+, and Sc3+, as they all have the same number of electrons as argon.

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 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.
A chloride ion has the same number of electrons as a neutral atom of what element?
A chloride ion (Cl-) has the same number of electrons as a neutral atom of the element argon (Ar).
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas 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.
A chloride ion has the same number of electrons as a neutral atom of?
A chloride ion has the same number of electrons as a neutral atom of an element in Period 3 of the periodic table, as both consist of 17 electrons.
Which would have the same number of electrons as s2-?
Argon (Ar) would have the same number of electrons as S2-. Argon has 18 electrons, while S2- has 18 electrons as well, after gaining two electrons to achieve a full octet like noble gas configuration.
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.
Neutral atoms of argon atomic number 18 have the same number of electrons as each of the following items except?
Neutral atoms of argon (atomic number 18) have 18 electrons. Consequently, they do not have the same number of electrons as hydrogen (1 electron), helium (2 electrons), or lithium (3 electrons).
