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

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

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
10.
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
