Iron is the very last product in stellar fusion is that; Iron has a tightly bound nucleus, and atoms larger than iron are less stable and tend to undergo nuclear fission.
The stability of an atom is dependent on the binding energy per nucleon of the atom.
The binding energy per nucleon of elements increases steadily until iron, we can see that from the curve very easily.
Beyond iron, we have exceeded the region of stable binding energy per nucleon of atoms. The atoms after iron in the curve are mostly unstable heavy nuclei.
