Noble Gases – Periodic Table
What are the Noble Gases
The noble gases are a group of six inert (nonreactive) gases on the far right side of the periodic table. They are members of group 18, the last group on the periodic table.
All of the noble gases occur in the atmosphere.
In fact, air is 0.934% argon, while the other group 18 elements are present in much smaller quantities. Most of this argon in the air arises from the decay of radioactive potassium-40. Neon makes up .0018% of air, helium .00052%, krypton .00011%, and xenon .000009%.
Properties & Uses of the Noble Gases
The noble gases are tasteless, odorless, colorless, nonflammable, and mostly nonreactive.

These monatomic gases also conduct electricity and can fluoresce. Because of their nonreactivity, one organic chemist even referred to them as the “lazy elements.” However, Neil Bartlett showed us another side to these elements in 1962 by discovering a compound of xenon.
The noble gases all have very low melting an
