-Helium is colorless, odorless and non toxic
-It's boiling points are the lowest among the elements and it exists only as a gas except in extreme conditions
--Next to hydrogen, it is the second most abundant element in universe, and accounts for 24% of the elemental mass of our galaxy.
-Helium is the second lightest element and is the second most abundant in the observable universe, being present in the universe in masses more than 12 times those of all the heavier elements combined. Helium's abundance is also similar to this in our own Sun and Jupiter.
-Helium is commercially recovered from natural gas deposits, mostly from Texas, Oklahoma and Kansas.
-Helium gas is used to inflate blimps, scientific balloons and party balloons. It is used as an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic wind tunnels. Helium is combined with oxygen to create a nitrogen free atmosphere for deep sea divers so that they will not suffer from a condition known as nitrogen narcosis. Liquid helium is an important cryogenic material and is used to study superconductivity and to create superconductive magnets.
