Conflicting experimental evidence for metal foam formation in aluminium-doped helium . 72 Domestic Production and Use The estimated value of GradeA helium (99.997% or better) extracted domestically during 2011by private industry was about $808millionNine plants (five in Kansas and four What is Helium?. The atomic number of helium is 2, meaning each atom of helium has two protons.. Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas except under extreme conditions..
