What chemical is more abundant the older a star is?
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
What is the name for a star that fuses hydrogen into helium?
A star that fuses hydrogen into helium is called a main sequence star. This is the stage in a star's life cycle where it is converting hydrogen into helium through nuclear fusion in its core, resulting in the release of energy.
Which of the following steps in a star's life cycle takes the longest?
The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
What is a medium size yellow star composed mostly of hydrogen and helium?
All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.
What are the 3 main fuels stars us for fusion?
The three main fuels stars use for fusion are hydrogen, helium, and trace amounts of heavier elements like carbon and oxygen. In the core of stars, hydrogen fuses into helium through a series of nuclear reactions, releasing energy in the process. This fusion process powers the star and allows it to shine.
Why do you have helium?
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
How does the CNO cycle differ from the proton-proton chain?
The CNO cycle uses carbon, nitrogen, and oxygen as catalysts to convert hydrogen into helium, while the proton-proton chain fuses hydrogen into helium directly. The CNO cycle is more efficient in high-mass stars while the proton-proton chain dominates in lower-mass stars like the Sun.

What fuses hydrogen to form helium?
Nuclear fusion is the process that fuses hydrogen atoms together to form helium. This process occurs in the core of stars, including our sun, where high temperatures and pressures allow hydrogen nuclei to overcome their electrostatic repulsion and combine to form helium nuclei.
What is a medium size yellow star composed mostly of hydrogen and helium?
All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.
Do small stars have hydrogen and helium?
All stars contain hydrogen and helium.
Which phase represents the longest period of time in a star's life cycle?
The main sequence phase represents the longest period of time in a star's life cycle, during which the star fuses hydrogen into helium in its core. This phase can last billions of years, depending on the mass of the star.
What are the two main elements found in the stars?
Hydrogen and helium
What kind of power is generated in stars?
Nuclear fusion is the process that provides energy to the stars.The star fuses hydrogen to form helium this is a process that gives out a lot of energy,stars which are more passive than our sun then it fuses the helium atoms to form carbon.
What element is created in the center of stars?
The element created in the center of stars through nuclear fusion is primarily helium. Initially, hydrogen fuses together to form helium under the extreme pressure and temperature conditions within a star's core.
