Create 3 circles around each other and put 18 electrons in those 3 circles. Starting with 2, then 8, and 8 again.
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
argon
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.
It doesn't become an argon atom because it (Cl-) still has 17 protons, and an argon atom has to have 18 protons.
Argon does not contain valence electrons.

argon
Argon.
argon
Yes. Because argon is an element the smallest "piece" of it is referred to as an atom.
An atom of argon has a completely filled outer shell. If you know about bonding, you will get what I mean. The argon atom does not want to give or receive or give electrons because it is already as stable as possible.
This is not really a question. If you want to build an animated version of an atom then there are plenty of websites out there. If you want to build a physical model you could use anything from Styrofoam balls to jelly beans.
i think it is an atom
