Helium (He #2) is the next element on the periodic table for my APEX mineral collection.

Helium Minerals - There ZERO Helium minerals.

Helium is our first Noble gas.  That means it won't react with anything and can't create minerals.

Helium on Earth is rare.  What exists is created by the radioactive decay of 

Thorium and Uranium.  This Helium is trapped with natural gas in concentrations up to 7% by volume.

Helium boiling and melting points are the lowest of any element. It exists only as a gas except in extreme conditions.  Helium represent 24% of the total mass of the universe.  So now, with Hydrogen, we have accounted for 99% of the total mass of the universe.

Helium is used for many purposes that require some of its unique properties, such as its low boiling point, low density, low solubility, high thermal conductivity, or inertness. Most Helium is used in cryogenic applications. 

Helium has no biological role.
