Why does your sun have 2 percent heavier elements and from where do they come?

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.

Which process combines lighter elements into heavier elements and produces energy within the sun and other stars?
That is called "nuclear fusion".
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 is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
Why can the Sun not produce heavier elements beyond carbon and oxygen?
The sun does not have enough mass or a hot enough core to fuse heavier elements such as carbon and oxygen.
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.
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.
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.
How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
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.
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 are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.
What are five objects that form the sun?
The sun is formed of hydrogen and helium, and a small amount of heavier elements. All of it is in the form of gas or plasma.
What elements make up about 25 percent of the mass of the sun?
helium
