which gets heavier elements from fusion of hydrogen and other light elements.
Edit: Our Sun does create helium from hydrogen by fusion, but that's all. The reason it has heavier elements is that these come from the nebula that formed the Sun. The heavier elements are thought to have come from stars that exploded as "supernovas", a long time ago.
What else can I help you with?
Which process combines lighter elements into heavier elements and produces energy within the sun and other stars?
That is called "nuclear fusion".
What is the evidence that your sun is a second or third generation star?
The Sun is considered a second-generation star based on its composition and the presence of elements heavier than hydrogen and helium, such as carbon, oxygen, and iron, which are remnants of earlier generations of stars. Stellar nucleosynthesis in these previous stars produced these heavier elements, which were later expelled into the interstellar medium when those stars died, enriching the gas and dust from which the Sun formed about 4.6 billion years ago. The abundance of these heavier elements in the Sun's spectrum indicates that it formed from material that had already undergone at least one cycle of stellar evolution. Additionally, studies of solar system formation support this idea, as the presence of such elements is consistent with a solar nebula influenced by earlier stellar explosions, like supernovae.
Bernard's star has a mass of how many times the mass of sun?
15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
If a star runs out of fuel when all of the elements inside it are fused to iron how are the heavier elements created?
During the main life cycle of a star, no elements heavier than iron can be created, and that's only in very massive stars (our sun is only massive enough to fuse hydrogen into helium). Your question is a very good one, and if you thought of it on your own, you should be proud. Every element heavier than iron is created when the star dies. Specifically, when it becomes a super-nova. When all the lighter elements have been fused, the star can't generate enough energy to resist its own gravity, so it collapses in on itself. The result is a sudden gigantic spike in pressure that creates all the heavier elements. As if it weren't cool enough that we're all made from star-stuff, a good bit of us is made from supernovae, too!
What percent of the sun is composed of helium?
About 25% (according to the Wikipedia article "Sun").
How does uranium come from the sun?
Uranium is not directly produced by the sun. Uranium is formed through the process of supernova nucleosynthesis during the explosion of massive stars. Elements like uranium are created during supernova explosions, where the intense heat and pressure fusion lighter elements into heavier ones.
Is stars the size of the sun can produce elements heavier than oxygen true or false?
True. Our Sun will eventually produce elements as heavy as iron.
Why can the Sun not produce heavier elements beyond carbon and oxygen?
The Sun can only produce elements up to carbon and oxygen through nuclear fusion in its core. For elements heavier than carbon and oxygen, higher temperatures and pressures are required, which can only be achieved in more massive stars or during supernova explosions.
Which elements found in the sun are also present in human body?
Well all natural elements (leaving out the man made ones) come from solar nuclear reactors. The sun is still mostly hydrogen and helium, with some carbon and iron, possibly less quantities of the heavier elements. It's not big enough or hot enough to produce more of the heavier elements, which come from much larger and hotter stars or supernovae. Those probably came from the planetary nebula from a previous stellar explosion which coalesced into our planet and us.
What chemical elements compose more than 98 percent of the sun?
The sun's composition is dominated by two primary chemical elements, which together account for more than 98 percent of its mass. Hydrogen, the lightest and most abundant element in the universe, makes up approximately 74 percent of the sun's mass. Helium, the second lightest element, comprises about 24 percent of the sun's mass, bringing the total to 98 percent. The remaining 2 percent consists of various heavier elements, including oxygen, carbon, nitrogen, and iron, among others.
What it a process in which lighter elements stick together to create heavier elements?
This process is known as nuclear fusion. It occurs in stars like the sun when lighter elements such as hydrogen are combined to form heavier elements like helium, releasing a large amount of energy in the process.
Which process combines lighter elements into heavier elements and produces energy within the sun and other stars?
That is called "nuclear fusion".
What is the sun formed from?
hydrogen, helium, and a small amount (less than 2%) of heavier elements
True or False - Stars the size of the sun can produce elements heavier than oxygen.?
True
What is the term describing the fusing of lighter elements into heavier elements?
That process is known as nuclear fusion. In nuclear fusion, lighter elements such as hydrogen combine to form heavier elements, releasing energy in the process. This is the process that powers stars like our sun.
What percent of the sun is water?
None. The sun is made of pure elements, mostly hydrogen, which fuse together, creating energy in the form of heat and light. When the hydrogen has fused into helium, the helium fuses into the heavier elements. Eventually, a couple billion years in the future, the sun will be made almost entirely of iron, at which point the fusion will cease and the sun will DIE. But you won't be around to see it. At no point does water form without it being immediately consumed and fused into heavier elements.
What is the main materials in the sun?
The Sun is primarily made up of hydrogen and helium, with smaller amounts of heavier elements such as carbon, oxygen, and nitrogen. These elements undergo nuclear fusion in the Sun's core to produce energy and light.
