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.
How is it possible to know that the element hydrogen exists throughout the universe?
Hydrogen is the most abundant element in the universe due to its simple atomic structure and presence in stars. Scientists observe hydrogen through its spectral lines in the light emitted from stars and galaxies, confirming its widespread existence. Additionally, studies of cosmic microwave background radiation and the chemical composition of various celestial bodies provide further evidence of hydrogen's presence.
What is the number one element in the universe that is burned in stars?
Hydrogen is the most abundant element in the universe and is the primary element that is burned in stars, particularly in the process of nuclear fusion to form helium.
What element is the most abundant in the universe and all stars are made of it?
The most abundant element in the universe is hydrogen.
What element provides most of the fuel for stars of all sizes?
Hydrogen
Stars primaily burn what element as fuel?
Hydrogen.
What is the chemical composition off most stars?
Stars contain hydrogen, helium and a little iron.
Which are two abundant element in the stars?
Hydrogen and helium are the most abundant elements in stars.
What are the original elements?
The original element is hydrogen. All others were synthesized ("cooked") in the interiors of stars, after the stars contracted out of clouds of hydrogen.
How did scientist discovered that stars were made up mostly of hydrogen since stars are so far away rom earth?
Scientists studied the light emitted by stars and found that the spectral lines corresponded to those of hydrogen. By analyzing these spectral lines through spectroscopy, scientists were able to identify the elements present in stars, with hydrogen being the most abundant element. This discovery revolutionized our understanding of the composition of stars and the universe as a whole.
What Is the lightest element and makes up the sun and stars?
Hydrogen.
What element is used as the primary fuel source for stars?
hydrogen
