Number of protons = Number of electrons = 18Number of neutrons:
Argon has 18 electrons and protons...Neutrons is 22
Argon-39 has 18 protons, 21 neutrons, and 18 electrons.
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%
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
Argon atoms are made from protons, neutrons and electrons.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Protons: 18Neutrons: 18, 20 and 22. Electrons: 18
Argon has 18 protons and 22 neutrons in the nucleus. It has 18 electrons surrounding the nucleus with 2, 8 and 8 electrons in the three shells.
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
Neutrons = 24 Protons = 18 Electrons = 18
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.
This is the isotope argon-31.
