Helium is a 2014 Danish short drama film directed by Anders Walter. Ramsay obtained a sample of the uranium-bearing mineral cleveite, and, upon investigating the gas produced by heating the sample, he found that a unique bright yellow line in its spectrum matched that of the D3 line observed in the spectrum of the Sun; the new element of helium was thus conclusively identified. It is called a noble gas because it doesn’t chemically interact with elements. Hydrogen has a single proton in its nucleus while helium has two.
