The same as its atomic number (18)
The element with 18 protons and 22 neutrons is argon. Argon has an atomic number of 18, which corresponds to the number of protons, and an atomic mass of 40 (approx.), which is the sum of protons and neutrons.
There are 18 protons in each atom.
Yes. The atomic number of chlorine is 17 and it has 17 protons. The atomic number of argon is 18 with 18 protons.
Argon is a non metal element. Atomic number of it is 18.
The atomic number of argon is 18, which means it has 18 protons in its nucleus. The mass number of argon is 40, which is the sum of protons and neutrons in its nucleus.

There are 18 protons in each atom.
Argon atoms have 18 protons which is similar to the number of electrons.
Yes. The atomic number of chlorine is 17 and it has 17 protons. The atomic number of argon is 18 with 18 protons.
Argon has 18 protons
It is the mass number, i.e., the total number of protons and neutrons in argon and is ofter used to calculate the number of neutrons present. As the atomic number (or the number of protons) for argon is 18, there will be 22 neutrons in Argon-40 isotope.
Because the number of protons in chlorine atom and chloride ion are the same (17 protons). The element argon has 18 protons.
Argon is a non metal element. Atomic number of it is 18.
In its non-ionized state, which is usually how it is found since it's an inert gas, argon has 18 electrons.All atoms have the same number of electrons and protons. According to the periodic table, argon has 18 protons. It therefore also has 18 electrons.Number of Protons/Electrons: 18
