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.

∙ 14y agoThe most common element in the universe is (we believe) hydrogen, and the second most common is helium. Hydrogen is the primary element of star formation, and during most of a star's life, it fuses hydrogen into helium.
When a massive star dies, it explodes in a titanic burst of fusion energy in which the helium and other heavier fusion products are re-fused into still heavier elements. This is the source of all of the heavier metals and elements from carbon up to uranium and beyond.

What are the two main elements in the stars?
Hydrogen and helium
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 the three main elements that determine a stars brightness from earth?
1) absolute brightness 2) distance 3) intervening dust
How many stars are in the constellation puppis?
2 main stars
What are all of the elements found in the core of a star?
For stars on the main sequence, Hydrogen and helium.

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.
Compare the elements formed in the big bang with elements formed through nuclear fusion in stars?
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.

1) absolute brightness 2) distance 3) intervening dust
What two elements are the most common stars?
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
Element abundantly present in the universe especially in stars?
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

2 main stars
What are all of the elements found in the core of a star?
For stars on the main sequence, Hydrogen and helium.
What are some of the elements found in stars?
All of them - but mostly hydrogen & helium.
What are elements main features?
The main group elements are groups 1, 2, and 13 - 18.
