Shortly after the big bang, the first stars were formed - Population III stars. These comprised of nothing more than hydrogen and helium and maybe a little lithium for good measure. When these stars died, they would have exploded as massive supernova and spread the first 26 elements into the Universe.
These 26 elements would have mixed with hydrogen and helium to make the next set of stars - population II stars. Most of these stars, when they died, would have exploded as supernova, enriching the Universe with the rest of the elements.
These elements, along with even more hydrogen and helium, combined to make our Sun. Our Sun is a metal rich star or population I star.
Just in case your wondering what the next set of stars will be called, I have no idea - Population 0 maybe?

Gas giants have atmospheres composed primarily of helium and what?
Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.Hydrogen and helium, the most common elements in the Universe.
What two elements are found in stars?
hydrogen and helium. More than just these two elements can be found in stars, though, otherwise we would live in a universe comprised completely of hydrogen and helium.
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.
Why is hydrogen and helium found in all stars?
These elements are found in are very important in each of the five stars. all five stars because the elements
Are the sun moon and stars elements?
No
What are some differences between pop I and pop II stars?
Population I is younger and has more heavy elements. Population II is older and is almost entirely hydrogen and helium.
How do Population One and Population Two stars compare to each other?
Population I stars have more metals (heavier elements), and are generally younger, than the Population II stars. It is postulated that there are still older Population III stars, that have even less metals and are even older, but none have been discovered yet.
Since the Earth is made up largely of heavier elements what would you conclude about its relative age?
The earth is younger then most stars and is made up from the remains of dead stars.
What element would be more commonly found in older stars than in younger stars?
Chemicals between carbon and iron.
How elements are formed in stars?
By nuclear fusion and neutron captureRight now the sun is fusing hydrogen into helium.Later in its life it will fuse helium into carbon.All elements are made inside stars. Massive stars are more efficient than low mass stars at making elements heavier than carbon.

Are all-stars made of similar elements?
Younger stars often are made up mainly of hydrogen, perhaps with some helium. Less massive stars will only fues hydrogen into helium, so eventually they will end up having a lot of helium. More massive stars however will eventually start fusing helium to metals, i.e., heavier elements. In any case, the "metallicity" (percentage of elements heavier than helium) and the percentages of different elements should vary somewhat between different stars.Younger stars often are made up mainly of hydrogen, perhaps with some helium.

What is the factories of elements?
If the question is where are elements made, the answer is in stars.
Name the gases that make up most stars?
Hydrogen and helium. It's better to ask which two ELEMENTS make up the bulk of the stars, since ALL elements in a star are in the gaseous state.
Why is hydrogen and helium found in all stars?
These elements are found in are very important in each of the five stars. all five stars because the elements
