What are the Noble Gases?

The Noble Gases are found in the right-hand column of the Periodic Table, family 18. A Noble Gas is stable because it has eight electrons in its outer orbital. All of the Gases in this family were believed to be inert or non-reactive. However scientists have been able to react Xenon, Radon and Krypton with Fluorine. Noble gases are colourless, odourless, and nonflammable. Helium is used to fill hot air balloons. Neon is used in fluorescent lighting. [LM] {CI}
