Argon-36 has 20 neutrons. This is determined by subtracting the atomic number (number of protons) from the Atomic Mass. Argon has an atomic number of 18, so when you subtract 18 from the atomic mass of 36, you get 20 neutrons.
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-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).
Argon-39 has 18 protons, 21 neutrons, and 18 electrons.
Argon has 18 electrons and protons...Neutrons is 22
If you look at the periodic table, Argon's atomic mass is forty, and its atomic number is eighteen. So forty minus eighteen = 22 neutrons
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.

There are 18, 20 or 22 neutrons.
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%
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.
An isotope is an atom with a different number of neutrons. The number of neutrons is the only particle that changes. Electrons will stay the same. Therefore, the number of electrons is the same as the atomic number, which is 18.
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).
Argon-39 has 18 protons, 21 neutrons, and 18 electrons.
Argon has 18 electrons and protons...Neutrons is 22
If you look at the periodic table, Argon's atomic mass is forty, and its atomic number is eighteen. So forty minus eighteen = 22 neutrons
No, they have the same atomic mass, which is the number of protons plus the number of neutrons. No two elements have the same atomic number.
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
