NOBLE GASSES

Noble Gases

• All noble gases have one valence electron and are in the nonmetal family
• Everything on the Periodic Table are categorized
• Into groups where columns and and periods in horizontal rows
• Nobles Gases is located in Group 8A
• All Noble Gases contain 8 valence electron

Elements In Noble Gases

• Helium
• Neon (Ne)
• Argon (Ar)
• Krypton (Kr)
• Xenon (Xe) and Radon(Rn)

Physical Properties

• Noble Gases are not reactive 
• They have little tendency to gain or lose electrons
• They have complete valence electrons
• The noble gases have low boiling points and are all gases at room temperature

Used In Everyday Lives

• Used in the industry of welding
• To dilute the oxygen in deep-sea diver
• Helium is used too too inflate tires of large aircraft, balloons, blimps 
• Neon is used in sign tubing because it glows bright colors
• Krypton and xenon are used in photographic flash units and in lighthouses  

What Do They Look Like

• They are odorless
• Colorless 
• Monatonic gasses with low chemical 

Where are They Located Article 1

• Noble Gases are rather uncommon on earth
• They make up about 1 percent of Earths atmosphere
• They are mostly detected in small amounts in minerals in the Earths crust
• They are thought to have been released into the atmosphere long ago as by-products
• Of the decay of radioactive elements in Earth's crust

First Noble-gas Molecules Found in Space Article 2

• An international team of astronomers has accidentally spotted the first space molecules bearing a argon
• The surprising discovery, in the debris of an exploded star
• Reveals the element's isotopic composition
• Confirming long-standing predictions that argon is forged in such doomed stars

The Mysterious Case of the Missing Noble Gas Article 3

• Xenon, the second heaviest of the chemically inert noble gases, has gone missing
• Our atmosphere contains far less xenon, relative to the lighter noble gases, than meteorites 
• Similiar to the rocky material that formed the Earth
• The missing-xenon paradox is one of science’s great whodunits
• It's not really missing it's just hiding somewhere
