Question

hydrogen gas is most abundant gas in universe.The second most abundant gas is helium. Than why helium is present in so much less rate on Earth??

Answer 1

Hydrogen is the most abundant element in the Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number;oxygen has abundance rank 3, but atomic number 8. All others are substantially less common. Hope this is helpful to you
