Uranium isotopes refer to different forms or versions of uranium. Isotopes are like different flavors of the same element. They have the same number of protons but different numbers of neutrons. Uranium, a heavy metal, has three main isotopes: uranium-238, uranium-235, and uranium-234. These isotopes are important because uranium-235 can be used as fuel in nuclear reactors or weapons, while uranium-238 is used to make depleted uranium for certain military applications.
