Argon is atomic number 18. It would therefore have 18 protons. Having 18 protons would mean that Argon must also have 18 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Argon typically does not form ions because it has a full outer electron shell. This stable electron configuration prevents argon from gaining or losing electrons to form ions.
The electron configuration of argon is [Ne] 3s2 3p6. From this, we can see that the outer shell contains eight electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

Germanium has 32 electrons in its electron cloud.
A chlorine atom typically has 17 electrons in its electron cloud.
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
Argon has 8 valence electrons (electrons in the outer shell)
In a neutral atom, the charge on the electron cloud is balanced by the carge on the atom's nucleus. The nucleus has a positive charge proportional to the number of protons in it. This attracts and holds the negatively charged electrons in the electron cloud. And in a neutral atom (not an ion), there will be as many electrons in the electron cloud as protons in the nucleus. The charges will balance.
The first energy level in the electron cloud can hold a maximum of 2 electrons.
