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.
What else can I help you with?
Do all galaxies contain billions of stars?
Yes, most galaxies contain billions of stars. For instance, our Milky Way galaxy is estimated to have around 100 to 400 billion stars. However, there are smaller galaxies, known as dwarf galaxies, that may contain as few as a few million stars. Despite this variation, the majority of galaxies are star-rich and typically hold vast numbers of stars.
What is the chemical composition of most stars?
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.
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.
Are there any elements in a neutron star?
No. Due to the massive gravitational pull - all atoms have been reduced to major and minor subatomic particles clumped together. Therefore, there are no discernible individual atoms and hence no elements.
What is the two building blocks of stars?
The two main building blocks of stars are hydrogen and helium. These elements make up the majority of a star's mass and are crucial for the nuclear fusion reactions that power a star's core and produce energy.
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?
Scientists believe that stars contain the same elements as the solar system because all elements in the universe are created through nuclear fusion in the cores of stars. Elements are dispersed into space when stars explode as supernovae. These elements then form new stars, planets, and other celestial bodies, resulting in the similarities in elemental composition between stars and our solar system.
What contain most of the heavier elements in the Milky Way population stars 1 or 2?
Population I stars
What are majority of the elements made of?
The majority of elements in the universe are made of hydrogen and helium, which are the two lightest and most abundant elements. Other elements are formed through nuclear fusion processes in stars or during supernova explosions.
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 is the chemical composition of most stars?
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.
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.
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 is the two most abundant elements in the nebulae?
The two most abundant elements in nebulae are hydrogen and helium. These elements make up the majority of the mass in interstellar clouds and are the building blocks for the formation of stars and planets.
Are there any elements in a neutron star?
No. Due to the massive gravitational pull - all atoms have been reduced to major and minor subatomic particles clumped together. Therefore, there are no discernible individual atoms and hence no elements.
