It is extracted from the natural gas by a low temperature separation process called fractional distillation. After its creation, part of it is trapped with natural gas in concentrations up to 7% by volume. On Earth it is created by the radioactive decay of much heavier elements ( alpha particles are helium nuclei). In the modern universe almost all new helium is created as a result of the nuclear fusion of hydrogen in stars. Helium is the second most abundant and second lightest element in the universe, and is one of the elements believed to have been created in the Big Bang. The behavior of liquid helium-4's two fluid phases, helium I and helium II, is important to researchers studying quantum mechanics (in particular the phenomenon of superfluidity) and to those looking at the effects that temperatures near absolute zero have on matter (such as superconductivity). It has a second, rare, stable isotope which is called helium-3. Extreme conditions are also needed to create the small handful of helium compounds, which are all unstable at standard temperature and pressure.
Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.

Helium ( He) is a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas series in the periodic table and whose atomic number is 2. * Atmospheric value, abundance may differ elsewhere.
