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.
The Most Abundant Elements. With only one proton, hydrogen is the simplest, lightest element, followed by helium, which has two protons. At 75 percent, hydrogen is also the most abundant element in the universe, followed again by helium at 23 percent, then oxygen at 1 percent. Each oxygen atom has eight protons. All of the other elements make up the remaining 1 percent. In the earth's crust, oxygen (47 %) is the most abundant element, followed by silicon (28 %) and aluminum (8 %).
