Hydrogen is the most common element in the universe, not oxygen.Oxygen is the most common element on Earth, followed by silicone.
On planet earth, silicon is the second most abundant element. It comprised 28 percent of the earth's crust. The most abundant is oxygen, which makes up about 47 percent of the earth's crust. The second most abundant element in the universe is helium.
Helium is an element. It is a noble gas. It is in the 18th period.
Helium is believed to be the second most abundant element in the universe, because the energy of most stars arises from the fusion of hydrogen to produce helium.
