There are 18, 20 or 22 neutrons.
18 protons and 18, 20 or 22 neutrons.
The nucleus contains 18 protons and neutrons. The number of neutrons depends on the isotope of argon. Ar-20, the most common isotope of argon has 22 neutrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Over 99.999% of argon is not radioactive. A trace of radioactive argon-39 can be found in nature, but it is not significant. Synthetic radioactive isotopes of argon exist, as they do for all elements.
There are 6 2p electrons in argon.
Argon has 22 neutrons.
22
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
neutrons = 40 - 18 = 22
Argon has 18 electrons and protons...Neutrons is 22
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.
18 protons and 18, 20 or 22 neutrons.
The most stable isotope of Argon has 22 neutrons (Ar40)
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 nucleus contains 18 protons and neutrons. The number of neutrons depends on the isotope of argon. Ar-20, the most common isotope of argon has 22 neutrons.
i will say 18 neutrons and electrons
Neutrons = 24 Protons = 18 Electrons = 18
