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.
Hydrogen: the essentials. Note that while hydrogen is normally shown at the top of the Group 1 elements in the periodic table, the term alkaline metal refers to the Group 1 elements from lithium downwards and not hydrogen. Hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about about 90% of the universe by weight. It is also the most abundant element in the earth's sun. Hydrogen as water (H 2 O) is absolutely essential to life and it is present in all organic compounds.
