Detailed explanation-1: -About 75% of the matter in the universe is hydrogen and the remaining quarter is helium. All the other elements are relatively rare to find.
Detailed explanation-2: -The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid.
Detailed explanation-3: -The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe.
Detailed explanation-4: -Approximately 11.3% of all atoms in the universe are helium atoms. When this number is added to the 88.6% of the atoms in the universe that are hydrogen, scientists conclude that at least 99.9% of all atoms in the universe are either hydrogen or helium atoms.
