Best Answer: Hydrogen and Helium. Not only are they the most abundant elements in the Sun, they're also the most abundant elements in the universe.
In living things (plants, animals, people) the six most abundant elements are carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. The universe is dominated by the elements hydrogen (83%) and helium (16%) The outside of the earth is a thin crust which is approximately 20 to 40km thick.
