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.

Which of the elements does a star contain?
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.
What percentage of stars are binary stars?
55%
Why are stars referred to as atomic furnaces?
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
What is the chemical composition of most stars?
The 2 most common chemicals found in stars are hydrogen and helium.
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
What element are stars mostly composed of?
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.
Why do scientists believe that stars contain the same elements as the solar system?
The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.
What contain most of the heavier elements in the Milky Way population stars 1 or 2?
Population I stars
What are the main elements that make up a star?
For main sequence stars, the vast majority is hydrogen and helium. Older stars will exhaust these lighter elements near their cores and begin fusing heavier elements.
What are some of the elements found in stars?
All of them - but mostly hydrogen & helium.
Why does the universe contain less hydrogen then it used to?
Some of the hydrogen has been converted into heavier elements by stars.
What kind of stars are mainly composed of hydrogen?
All stars are mainly composed of hydrogen. Stars also contain small amounts of helium and trace amounts of other elements such as nitrogen, oxygen, and carbon.
What periodic elements are in the star delta scorpii?
Stars contain hydrogen and helium and some other minor constituents as metals.
Where in the galaxy are most stars born?
Stars are born in areas of space that contain a high enough density of molecular hydrogen to cause fusion. These areas of space are known as molecular clouds and are the locations in space where the majority of stars are created.

Did the first protostars have contain elements heavier than hydrogen and helium?
According to the calculations done, it is assumed that right after the Big Bang there was only hydrogen, helium, and small amounts of lithium. There wasn't enough time to form other elements. Therefore, the first stars must have contained only such elements. No such stars - which would be considered "Population III stars" - have been found yet.
Are all-stars made of similar elements?
Younger stars often are made up mainly of hydrogen, perhaps with some helium. Less massive stars will only fues hydrogen into helium, so eventually they will end up having a lot of helium. More massive stars however will eventually start fusing helium to metals, i.e., heavier elements. In any case, the "metallicity" (percentage of elements heavier than helium) and the percentages of different elements should vary somewhat between different stars.Younger stars often are made up mainly of hydrogen, perhaps with some helium.
