Like hydrogen, helium is lighter than air, so when you fill balloons with helium, they float. BL-W02. The incident was not made public until a week later. Is helium flammable? ‘Even though helium is twice as dense as hydrogen, this is less than one metric ton of gas.’ ‘Argon is denser than air, and certainly helium, which means that it has more molecules to retain heat.’ ‘There he worked with Born on atomic theory, writing a joint paper with him on helium.’ It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heids the noble gas group in the periodic table. In his initial report to the French Academy of Sciences about the 1868 eclipse, Janssen made no mention of a yellow line in the solar spectrum. Helium-3 (3 He, tralphium, see also helion) is a light, stable isotope of helium with two protons and one neutron (the most common isotope, helium-4, having two protons and two neutrons in contrast).Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons. The first isolation of it was made by William Ramsay , Per Teodor Cleve, Abraham Langlet in 1895 and after that continuous experiments and thesis have been made on the same.  As pressure increases with depth, the density of the breathing gas also increases, and the low molecular weight of helium is found to considerably reduce the effort of breathing by lowering the density of the mixture.
