Radioactive Elements in the Continental Crust Nature

NettetUranium. Uranium is a trace element that occurs naturally in the earth's crust. All of the isotopes of uranium are unstable and are radioactive. The most abundant isotopes are 238 U and 235 U. The percentage abundance of 238 U is 99.25 percent and the abundance of 235 U is 0.75 percent. NettetUranium is a common element in Earth’s crust (soil, rock) and in seawater and groundwater. Uranium has 92 protons in its nucleus. The isotope 2238U has 146 neutrons, for a total atomic weight of approximately 238, making it the highest atomic weight of any naturally occurring element.
