How are elements formed?
Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
What is the typical composition of a star?
A typical star is primarily composed of hydrogen (~74%) and helium (~24%), with traces of heavier elements like carbon, oxygen, and iron. The core of a star undergoes nuclear fusion, where hydrogen is converted into helium, releasing energy in the form of light and heat.
What Elements Are Presently In The Star Aldebaran?
Aldebaran is a red giant star located in the constellation Taurus. It mainly consists of hydrogen and helium, with smaller amounts of heavier elements such as carbon, oxygen, and nitrogen produced through nuclear fusion processes in its core. These heavier elements were created during the star's evolution from a main sequence star to a red giant.
What is the composition of the planet Jupiter?
Jupiter is composed of mostly liquid metallic Hydrogen, some Helium, and molecular Hydrogen. There are thought to be a mixture of elements in the core.
What is the name of the stellar process in which the fusion of hydrogen produces other elements?
The stellar process in which the fusion of hydrogen produces other elements is called nucleosynthesis. This is a key process in the evolution of stars, where lighter elements such as hydrogen and helium are fused together to form heavier elements like carbon, oxygen, and iron.
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
What is the role of hydrogen and helium in the sythesis of elements?
Hydrogen and helium are the most abundant elements in the universe. And stars use them for power. To put it simply, hydrogen is fused into helium, and helium into carbon. All the heavier elements are made from there up through iron. The trans-iron elements are made is a supernova. It could be argued that hydrogen and helium are the basic building blocks of other elements.
Immediately after the Big Bang the universe contained?
Hydrogen, helium, small amounts of lithium. No heavier elements. Lots of the mysterious dark matter.Hydrogen, helium, small amounts of lithium. No heavier elements.

The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
What are the 2 main elements in stars?
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.
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
What elements are presented in the stars?
The most common element in the Universe - and in most stars - is hydrogen. Stars have smaller amounts of helium, and still smaller amounts of "metals" (heavier elements). Some stars may have burnt out their hydrogen, and consist mainly of helium and heavier elements. It really depends on the star's stage in its life cycle.
What is the fuel of a star in space?
Hydrogen , Helium and a few heavier elements.
Where did hydrogen and helium in the universe come from?
Hydrogen and helium were mainly produced during the Big Bang, the event that created the universe. Roughly 75% of the normal matter in the universe is hydrogen and about 25% is helium. These elements have since played a fundamental role in the formation and evolution of all other elements in the universe through processes like nuclear fusion in stars.
What are the two most common elements of the universe?
Hydrogen and helium.
Which of these elements does this star contain?
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.
