The sun and other stars are composed primarily of hydrogen and helium. The hydrogen atoms combine by nuclear fusion resulting in helium.
The fusion of atoms powers the sun and other stars!

Hydrogen?
Hydrogen atoms have one proton in their nuclei. When two hydrogen atoms fuse together they make one helium atom that contains two protons in its nucleus. This is called nuclear fusion, which powers the stars in the universe.
The main source of energy in the Sun and other stars is fusion of hydrogen atoms into helium atoms.
The sun and other stars are powered by fusing hydrogen into helium in their first stage of life. Then as they get older the hydrogen runs out and the fuse helium and on up onto iron. Heavier elements come from novas and super novas.
fusion
When two hydrogen atoms combine to form a helium atom, a process called nuclear fusion occurs. This releases a large amount of energy in the form of light and heat. This is the same process that powers the sun and other stars.
Nuclear fusion is the process that powers stars, such as our sun.
Stars are super-heated, ionized gas. This state of matter is called plasma, and yes, it's matter because it's made of atoms. Atoms have mass and volume.
It doesn't. The nuclear/chemical reaction that powers the other stars is entirely independent of what our sun is doing.
Way too many to count. The stars have many trillions of trillions of trillions of atoms. When a star is "born," it only contains hydrogen atoms. As time goes on, the star uses nuclear fusion to fuse these atoms together to form heavier elements such as iron. In affect, us humans are made of atoms created in stars.
