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 is the most abundant element, comprising about three quarters of the mass in the universe. Hydrogen is found in the water that covers 70% of the earth's surface and in all organic matter. Hydrogen is the simplest element in the universe. It is made up of one proton and one electron. Hydrogen is the lightest of all elements and gases, and is 14 times lighter than air. A gaseous hydrogen spill diffuses immediately into the air, and does not pollute the ground or groundwater.
