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.)
How are elements with nuclei larger than iron nuclei formed?
Supernova form heavier elements
What is a hypothesis to explain the presence of iron and other heavier elements than iron?
Chemical elements are formed in the Universe by stellar nucleosynthesis.
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.
How are elements formed from hydrogen?
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

What is the relationship between the periodic table and a supernova?
The elements on the periodic table were created by stars through nuclear fusion. We use the term stellar nucleosynthesis to describe what stars are doing through fusion. Stars fuse hydrogen into helium, and then start making heavier elements by a different fusion process. But stars can only make elements up through iron. They can't make the heavier elements. Enter the supernova. A supernova is that "big blast" that occurs at the end of the life of some stars. In a supernova, the trans-iron elements are formed. That is, all the elements heavier than iron are formed in a supernova. Because the elements heavier than iron are formed in a supernova, we can say that there is a relationship between the supernova and the periodic table of elements.
How are elements heavier than hydrogen formed?
They are formed inside of stars.
What atoms are heavier than iron?
There are many elements that are heavier than iron, including lead, gold, platinum, osmium, uranium, etc. Look at the periodic table of the elements.
Fusion in a dying star can also create heavier elements but none heavier than?
Iron
Massive stars cannot generate energy through iron fusion because?
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
What is produced within a star's core?
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
Where did all the elements come from?
Hydrogen, some helium and less lithium are the result of the big bang. All the other elements are made inside the cores of stars, except for elements heavier than iron. All elements heavier than iron are created during supernova explosions.
