The assumed helium sedimentation model, on average, produces a negligible increase in the gas mass inferred within large radii (r < r500) (1.3 +/- 1.2 per cent) and a (10.2 +/- 5.5) per cent mean decrease in the total mass inferred within r < r500.
Helium compounds - Wikipedia
Helium is the most unreactive element, so it was commonly believed that helium compounds do not exist at all. Helium's first ionization energy of 24.57 eV is the highest of any element. [2] Helium has a complete shell of electrons , and in this form the atom does not readily accept any extra electrons or join with anything to make covalent ...

Uses of Helium - Uses Of
Helium is one of the most common elements in the universe. It is called a noble gas because it doesn’t chemically interact with elements. Its atomic number is 2 and the weight is 4.002. In its natural state, it doesn’t have any smell, taste or color. Common Uses of Helium Evidence shows that the human voice can be changed with a bit of helium.
