Helium Vs Hydrogen
Hydrogen is first on the periodic table followed by Helium, so Hydrogen is a lighter element. Hydrogen is the most abundant element in the universe (makes up approximately 90% of the universe). Hydrogen is very reactive, which is why it is a bad choice for blimps (ie...the Hindenburg). Helium is a significantly heavier element and is found as He2 which makes it non reactive (non flamable).

Comments: Hydrogen is approximately half the density of helium. Though one might expect it to be 1/4 the density because it has 1/4 the atomic weight, hydrogen comes in the form H2, so one molar unit of hydrogen weighs only half that of helium. One molar unit of helium is just He, because helium never forms bonds EVER.
