Uranium occurs naturally in the Earth's crust and is mildly radioactive. It is the only element with a naturally-occurring fissile isotope.

WebThe stellar nuclear fusion process beings by hydrogen atoms fusing together to form helium. If the initial mass of the star is less than ~0.4 M, where M is the mass of our sun, then helium will be the final product.
