The sun would then be dead, and the solar system including all the planets would receive no more energy from the sun. Life on Earth would die out.
More Info:
It is thought that the sun is not large enough to fuse carbon into iron. It turns out it should fuse all of the helium and finally end leaving nothing but carbon. In fact, our sun will turn into a dwarf star which will resemble basically a planet sized diamond.
Stars that produce iron through fusion are usually much larger and produce supernovas. The heavy gravitational pull uses excess energy to fuse iron into the larger and more rare elements before blowing the entire star and core apart. This is how these heavy elements exist around the universe.
A massive star with iron in its core will stop nuclear fusion, leading to its collapse and eventual explosion as a supernova. Iron is the element at which fusion becomes endothermic, meaning energy is no longer released in the process.
Iron is the most massive element that can be formed by nuclear fusion with the liberation of energy. This is because fusion reactions beyond iron require an input of energy rather than liberating energy.
Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
Elements from helium to iron are primarily created through nuclear fusion in the cores of stars. Helium is formed by fusing together hydrogen atoms, while carbon, oxygen, and heavier elements up to iron are synthesized through additional fusion reactions as the star evolves. Iron is usually the endpoint of nuclear fusion in stars, as further fusion processes would require more energy than they release.
Existing element is product of nuclear fusion, heavy element exist from over fusion and thus create high atomic mass substance. To answer what is the element that is form last in nuclear fusion in star is the same as asking what is the heaviest element occur or found in nature. Base on what is in periodic table. The heaviest element found naturally is around Uranium - Plutonium thus it could be considered the last product known in nuclear fusion in star. There are heavier element than Uranium and Plutonium but those are synthesize element. Nuclear fusion might go to element heavier than what is known in our periodic table but those substance may be unstable and decay over time until none of those exist.

Yes, fusion is exothermic until nickel & iron are produced.
The process is called stellar nucleosynthesis and is based on nuclear fusion reactions.
They use nuclear fusion and the iron makes light escape.

Nuclear fusion: mainly of hydrogen into helium. To a lesser extent there is fusion of helium into larger elements - all the way to iron.
Nuclear Fusion
Nuclear fusion, which is the mechanism by which stars operate, will cause lighter nuclei to "combine" (fuse) to create heavier ones. It will also cause a lot of energy to appear. This is because the fusion reactions are exothermic (at least through fusion that creates elements up through iron).
Existing element is product of nuclear fusion, heavy element exist from over fusion and thus create high atomic mass substance.

After nuclear fusion, the next steps for a star depend on its mass. For lower-mass stars like our Sun, the core contracts and heats up, triggering helium fusion. For higher-mass stars, a series of fusion reactions occur with progressively heavier elements until iron is produced in the core. Once iron is produced, the star may undergo a supernova explosion or collapse to form a neutron star or black hole.
