Question

Why are the Noble gasses unreactive?

Answer 1

Noble gases are unreactive because they have a full outer electron shell. These gases (helium, neon, argon, krypton, xenon, and radon) all have complete electron configurations and are considered to be chemically stable. Because their outer electron shells are full, they have little to no tendency to gain, lose, or share electrons with other atoms. This stability makes them highly unreactive and non-reactive with most other elements or compounds under normal conditions.
