What is the heaviest element that our sun produces?

The sun currently fuses hydrogen into helium. It had no need to produce any heavier elements, which would require much more energy. When the sun starts going through the red giant phase, it will start to undergo something called the triple-alpha process, in which helium is fused into carbon. read more

Eventually, slow fusion of the heliun and carbon will cause the dying sun to produce its heaviest element: oxygen. The carbon-oxygen core will burn out, leaving fusion impossible. Heavier and larger stars may fuse the carbon into oxygen, and so on until they start producing iron. read more

The heaviest element that our Sun produces is probably silicon; the core temperature and pressure would need to be MUCH higher to produce heavier elements. The heaviest element that can be produced in ANY star is iron. The reason for this is something called the "packing fraction curve". read more
