Stars contain hydrogen, helium and a little iron.
The percentages vary quite a lot from one star to another. The general tendency, however, is that the majority of stars contain a large percentage of hydrogen. In general, hydrogen is the most abundant element in the Universe - for now. In the future, it will gradually be used up, and there will be less hydrogen, and more of the heavier elements.
Basically all of them. However, most stars contain large amounts of hydrogen (since that's the most common element in the Universe), as well as helium, as well as smaller amounts of other elements.
Most stars are composed primarily of hydrogen and helium, with hydrogen making up about 75% of their mass and helium about 25%. The remaining elements in stars are present in trace amounts, including carbon, oxygen, nitrogen, and other heavier elements.
Stars produce energy by fusing hydrogen into helium through a process called nuclear fusion. This fusion reaction releases a tremendous amount of energy in the form of light and heat, which powers the star and allows it to shine.
All stars contain hydrogen and helium.
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
Stars contain hydrogen, helium and a little iron.
Some of the hydrogen has been converted into heavier elements by stars.

Hydrogen and a small amount of Helium.
No. They don't contain rock particles that shine.

Main sequence stars, like our Sun, are mainly composed of hydrogen. These stars fuse hydrogen into helium in their cores, releasing energy in the form of light and heat. This process allows them to shine bright in the sky.
Stars have a similar bluish white color due to the gases that are inside of them. When you see stars that are bluish white you know that they contain a lot of hydrogen.
Hydrogen and Helium with a small amount of lithium. These are referred to as population III stars or low metal stars. See related question
