Helios, lit .' Sun') is a chemical element with symbol He and atomic number 2 . It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table . Its boiling point is the lowest among all the elements . </P> <P> After hydrogen, helium is the second lightest and second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined . Its abundance is similar to this figure in the Sun and in Jupiter . This is due to the very high nuclear binding energy (per nucleon) of helium - 4 with respect to the next three elements after helium . This helium - 4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay . Most helium in the universe is helium - 4, the vast majority of which was formed during the Big Bang . Large amounts of new helium are being created by nuclear fusion of hydrogen in stars . </P>
