Argon can be charged into an ionic form Ar+, however this is an extremely unstable species and will immediately recover the electron from a nearby atom or molecule. It is possible to stabilize a field of Ar+ ions in certain instruments to create what is called Inductively Coupled Plasma.
An argon ion can have a charge of +1, +2, or +3 depending on the number of electrons it has lost.
An ion with 18 electrons and a charge of -3 would be a chlorine ion (Cl^-). Chlorine normally has 17 electrons, but gaining one electron to form a chloride ion would give it a total of 18 electrons and a charge of -1. To have a charge of -3, two more electrons would need to be gained, resulting in a chloride ion with 18 electrons and a charge of -3.
Chlorine typically has a charge of -1 as an ion.
The oxygen 2- ion. The oxygen 2- ion gains two electrons and acts like neon.
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.

The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.
2- Because, to get a full octet, Sulfur gains two electrons to become like Argon, thus it gains a charge of 2-.
Chlorine typically has a charge of -1 as an ion.
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
The oxygen 2- ion. The oxygen 2- ion gains two electrons and acts like neon.
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.
Cl & K ions are isoelectronic with Ar.
Yes, argon can form ions, but it is less likely to do so because it is a noble gas with a full outer electron shell, making it stable and unreactive. It would require a significant amount of energy to remove an electron from argon to form an ion.
Argon
Chlorine can be found as an ion with a 1- charge by gaining one electron to achieve a full outer electron shell. This gives it the electronic configuration of argon, making it stable as a chloride ion (Cl-).
