Argon's atomic number is 18. thus, it has 18 protons and 18 electrons. Filling in the first 18 electron orbitals gives the configuration of 1s2 2s2 2p6 3s2 3p6. Thus, argon has 3 electron energy levels.

5
How many protons and neutrons does argon atom have?
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
How does an atom Argon-38 compare to an ordinary Argon-36 atom?
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.
What is the number of protons in the argon?
There are 18 protons in each atom.
An atom has what number of protons and electrons?
9 protons and 10 neutrons in F-19 isotope.
How many protons and electrons does argon have?
i will say 18 neutrons and electrons
When chlorine gains an electron to become a chloride ion with a -1 charge it ends up with the same electron arrangement as argon. Why doesn't it become an argon atom?
It doesn't become an argon atom because it (Cl-) still has 17 protons, and an argon atom has to have 18 protons.
What is a unique fact about argon?
Each atom of argon has exactly 18 protons and 18 electrons.
Why doesn't chlorine become an argon atom when it ends up with a noble gas electron configuration?
Because the number of protons in chlorine atom and chloride ion are the same (17 protons). The element argon has 18 protons.
How many neutrons are in the nucleus of an atom of argon-42?
Neutrons = 24 Protons = 18 Electrons = 18
How many protons are in a neutral atom of Ar-40?
Any atom of Argon (Ar) will have 18 protons regardless of charge or isotope.
How many protons are in the nucleus of Ar atoms?
It depends on the identity of the atom. For example, Hydrogen has one proton, but Helium has two.
What element has 18 neutrons in its atom?
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.
