 * 1) They are in group 18 and the 18th period of the periodic table.
 * 2) The six Noble Gases are Helium, Neon, Argon, Krypton, Xenon, and Radon.
 * 3) The Noble Gases are classified as Gas.
 * 4) Physical Properties: Helium in a balloon, Neon gas in a neon sign, or argon, xenon and/or any other noble gas in a neon sign.
 * 5) Chemical Properties: Usually unreactive, most are completely stable because most of the gases have 8 electrons covering the whole shell of the atom, and a few gasses only allow a few electrons to fill the outer shell.
 * 6) Interesting Facts: The noble gasses make up nine-tenths of 1% of the earths atmosphere, they do not usually react with any other element, and each gas glows its own color: Helium glows yellow, neon glows red-orange, and krypton glows blue-white, xenon glows blue, argon glows pale red at low temperatures and blue at high.
 * 7) Two common uses: Two common uses of the Noble Gases are most of the gases are heated and create a glow in neon signs and the second common use is helium in a balloon.
