Noble Gases

Why do neon signs contain other noble gases besides neon?

Neon signs are red-orange

any other color may be called neon signs, but actually have another gas in them.

each noble gas produces a different color when electricity is sent through

they contain only one gas at a time

What does the sun do with the helium?

In the Sun, helium undergoes thermonuclear fusion of hydrogen and it converts five million tons of matter into energy every second by nuclear fusion reactions in its core, producing neutrinos and solar radiation.

Noble Gases

What is so different About the noble gases when compared to other groups?

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable octet electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.

Other group elements do not obey octet rule and are thus generally reactive.

Why don't the noble gases in Group 18 on the periodic table form chemical bonds?

Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
