This element was originally used as a catalyst in the Haber process, and it is found in abundance in Saskatchewan. Its two major isotopes are 238 and 235, the latter of which was once referred to as "actino" this element. That former isotope of this element is useful since it decays to the fissile plutonium 239, and as such that isotope is frequently used in weapons. For 10 points, identify this element with atomic number 92 and symbol U.
