18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
9 protons and 10 neutrons in F-19 isotope.
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
18 protons and 20 neutrons
Neutrons = 24 Protons = 18 Electrons = 18
There is more than one isotope of argon (as there are of all elements) but the most common isotope is the one that has an atomic weight of 36; it has 18 protons, 18 neutrons, and 18 electrons. The same number for all three types of particles.
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
This depends on the individual Atom.
There are 18, 20 or 22 neutrons.
30 neutrons in Ni-58 isotope.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
"Used" is the wrong term to be used in this case. An atom is MADE up of protons,neutrons and electrons. Also, the number of protons or neutrons present in an atom depends on which atom is it or of which element it is.

Argon has 18 electrons.
Argon-38 is an isotope of argon with 21 neutrons. This can be calculated by subtracting the atomic number from the atomic mass number (38 - 17 = 21 neutrons).
