According to wikipedia, argon has 24 known isotopes. 40Ar is most abundant at about 99.6% of natural argon.
How do you say Charateristics?
Non metals are brittle.They are non lustrous. They have low melting point.
Argon has three full shells of electrons. Elements react to form bonds so that their outer shell is full. As Argon has a full outer shell it is unreactive
Oxygen, Nitrogen and Argon
Argon is found in the form of 3 isotopes: 40Ar, 36Ar and 38Ar (in order of abundance). All three are stable.
There are no common compounds of argon. The only known compound is argon fluorohydride but that is hardly common. Also, argonium (argon hydride) molecules have been identified in the Crab nebula, but that can hardly be described as common.
carbon-dioxide, argon and nitrogen
Neon, Xenon, Argon
There are over twenty known isotopes of argon. Of these all but three are radioactive and decay. Of naturally occurring argon, very nearly 100% is not radioactive, with only traces of one radioactive isotope found.
I think Argon is Stable, but I'm not 100% sure
