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 is the inner core believed to be compose of?
Solid iron, with impurities of other heavy metals
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
Is iron likely to be formed in the sun?
Not in our Sun, but heavy elements up to and including iron are formed in very massive suns (stars). Elements heavier than iron are formed with suns die in a supernova.
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.
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.)
Where is the early atmosphere thought to have come from?
It comes from the process of planetary differentiation. light elements such as nitrogen rise up to form the atmosphere,whereas heavy elements such as iron sink to the mantle.
Does a supernova fuse heavy elements into iron?
Yes. See related question.
What elements make up the innercore?
Heavy (or dense) ones ...mostly iron.
What is the inner core believed to be compose of?
Solid iron, with impurities of other heavy metals

Where are heavy elements like nitrogen and iron formed?
Such elements are formed within stars. The heavy elements which are currently here on Earth were formed in stars some time ago, and then they were blown into space in supernova explosions.
Where in the universe are heavy elements made?
Light elements are made in light weight stars via stellar nucleosynthesis. Elements as heavy as iron form in the cores of massive stars. Anything heavier than iron requires a supernova--the collapse and explosion of a super massive star.
What two elements make up earths core?
The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
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.
The heavy elements found on earth such as iron silver gold and uranium were created with the earth in a?
This process is called stellar nucleosynthesis.
