There are 3 Isotopes with the following mass numbers: Argon 36 Argon 38 Argon 40 Argon has an atomic number of 18 (it therefore has 18 protons in its nucleus and 18 electrons flying round it). To get the number of neutrons one subtracts the atomic number from the mass number. This means that some Argon atoms have 18 neutrons, some 20 neutrons and some 22 neutrons the isotope with 22 neutrons is the most common and forms 99.6% of all Argon.
Argon has 22 neutrons.
22
The element that has 18 neutrons is ARGON... Wow, why didn't look in a periodic table? Is easier ask here??? Actually, 18 is argon's atomic number, and it also has 18 protons and electrons.. but it has 22 neutrons. The number of neutrons = mass number - number of protons. Soo, the answer is Chlorine, 17 protons, 17 electrons and 18 neutrons
Argon has 18 electrons and protons...Neutrons is 22
18 protons and 20 neutrons
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.
neutrons = 22 (for the most stable isotope of argon, Ar-40)

The element Argon has 8 Isotopes argon-35, argon-36, argon-37, argon-38, argon-39, argon-40, argon-41 and argon-42.The stable isotopes of argon are:argon-36, 0.34%argon-38, 0.06%argon-40, 99.60%Of the radioactive isotopes argon-39 has the longest halflife at about 260 years, all the others have halflives measured in days or much less.
Argon has 22 neutrons.
There are 18, 20 or 22 neutrons.

Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
neutrons = 40 - 18 = 22
