The sun is made out of hydrogen atoms that have turned into plasma due to fusion. Plasma is the state of matter between a gas and a liquid not found in anything on earth except for lightning.

Right now, the Sun is converting approximately 400 million tons of hydrogen into helium every secondthrough the process of nuclear fusion. In fact, helium was first discovered in the Sun before it was discovered here on Earth. Anyway, the answer is mostly hydrogen and helium.

The sun is made of hydrogen and helium. The incredible gravity of the sun squeezes the nuclei of the hydrogen atoms together and fuses them into helium [hydrogen atoms have 1 proton; helium atoms have 2 protons; fusing two hydrogen atoms means 1 proton+1 proton=2 protons which is a helium atom]. Fusing releases a HUGE amount of energy. Scientists are trying to control fusion, but fusing even one atom makes so much energy it can melt every metal on Earth. Someone who finds out how to control fusion can earn TRILLIONS if not quadrillions of dollars.

In general, stars are big balls of gasses; but the matter in them is not in the same state as they would be here on earth. As they are very hot, they are composed of ionized atoms (just the nuclei) and a lot of energy. As mentioned, the particles at the center of a young star (like our sun) are in the process of nuclear fusion. Our sun is mostly hydrogen and helium nuclei, but as stars age you can see the formation of heavier nuclei. These can be observed by looking at the spectrum of radiation (including visible light) produced by stars.

mostly hydrogen and helium, but all the elements that make up our planet are created on the sun. Plasma is a state of matter, so that answer is correct, but that matter is hydrogen and helium.

The chemical composition of the sun:
Hydrogen...............73 %
Helium...................25 %
Oxygen................0.80 %
Carbon................0.36 %
Iron......................0.16 %
Neon...................0.12 %
Nitrogen..............0.09 %
Silicon.................0.07 %
Magnesium.........0.05 %
Sulphur...............0.04 %
Others combined....0.04 %
The sun is so hot that for the most part these elements are ionized, that is missing some or all of their electrons.
