The name "argon" is derived from the Greek word αργον, neuter singular form of αργος meaning "lazy" or "inactive", as a reference to the fact that the element undergoes almost no chemical reactions.

photon336 · Answer

noble gases are un reactive because they have 8 valence electrons, a filled shell; remember an elements reactivity will be based on how many valence electron that element has. some elements achieve octet by gaining electrons while others by losing electrons.
