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.
Argon's valence number is 8, it has 18 electrons, and its oxidation number is 0 because it doesn't react.
No. The atomic number of argon is 18. So it has 18 protons and 18 electrons (out of these, 8 electrons are valence electrons and belong to the outermost shell).

Yes. The ion Ca2+ and the element argon, have 18 electrons each.
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
