According to the Book on Astronomy written by Susan Douglas and Ryan Smith, they must be anything taller than a minimun of 1,200 m (meters)

Why are stars referred to as atomic furnaces?
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
What elements signal the end of a stars life?
I am not aware of any specific element "signaling" this. Towards the end of a stars life, however, relatively large amounts of heavier elements are produced.
Can stars the size of the sun produce elements heavier than oxygen?
Yes, oxygen can be found in the spectral lines of many stars. ---------------------------------------------------------------------------------------------------------------- Stars are nuclear fusion furnaces that take light elements (hydrogen) and build them up into heavier elements (eg carbon and oxygen). Thus older and second or third generation stars have this element in their makeup.
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.
Did gravity pulled the atoms together to form heavier elements?
No. Heavier elements were created by nuclear reactions in previous generations of stars.

Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
What is formed from stars?
All elements up to Iron are produced by smaller stars. heavier elements (everything heavier then iron) are produced from larger stars when they go supernova.

What are the heavier elements in this universe formed by?
a series of stars
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.
How did nuclear fussion in stars help create the elements?
Light elements combined to form the heavier elements.
How are elements heavier than hydrogen formed?
They are formed inside of stars.
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 contain most of the heavier elements in the Milky Way population stars 1 or 2?
Population I 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.
