All stars are comprised of around 98% hydrogen and helium, of which approximately 3/4 is hydrogen.
This is also true of all the matter in the universe as a whole.
While stars contain some amount of pretty much every element, they are made primarily of hydrogen and helium.
Hydrogen and helium
For stars on the main sequence, Hydrogen and helium.
Hydrogen and helium are the two main elements found in stars. These elements are formed through nuclear fusion in the cores of stars, where high temperatures and pressures enable the atoms to combine and generate energy.
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
Stars are primarily composed of hydrogen and helium, with smaller amounts of heavier elements. They generate energy through nuclear fusion in their cores, where high temperatures and pressures cause hydrogen atoms to fuse into helium, releasing energy in the process. Stars also have a structure that includes layers like the core, radiative zone, convective zone, and outer atmosphere.
Hydrogen and helium
The two main elements found in stars are hydrogen and helium. These elements are the most abundant in stars and are essential for nuclear fusion reactions that power a star's energy generation.
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
The two main elements in stars are Hydrogen and Helium. Stars start out as mostly Hydrogen and produce Helium. There are less amounts of heavier elements like Oxygen, Neon and Iron in stars
For stars on the main sequence, Hydrogen and helium.
All of them - but mostly hydrogen & helium.
The main group elements are groups 1, 2, and 13 - 18.
No elements were formed in the big bang. After quite some time, hydrogen began to form, and it is the main constituent of stars. The main by-product of nuclear fusion in stars is helium.
Hydrogen and helium
The main sequence stars are stars that fuse hydrogen, so the stars that have left the main sequence are the ones that have basically run out of hydrogen. They are the Red Giant stars, Supergiant stars and White Dwarf stars.
The 2 main stars are Will Ferrell and Nicole Kidman.
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
