joyeuxencore_11-5-12 I'm really bad at thinking up screen names. I choose xenon because it is one of the Nobel Gasses and I worked with it for years, so I can remember it. The other noble gasses are Argon, Neon, Raydon and 1 more I can't remember. Noble gasses don't mix with any other gas to form any kind of reaction. There, that is my chemistry lesson for the year.
