Helium (He) is an element.

Helium is the most inert element of all, and does NOT form compounds.

It is found in the Periodic Table as Atomic No. 2.

It has an Atomic Mass of '4'

Its symbol is [4/2]He

The name ' helium' comes Classical Greece, and means 'of the Sun(helios)'. Because two atoms of hydrogen in the Sun fuse together form 'helium'.
