ADU is mixed with hydrofluoric acid to produce this element's hexafluoride, and this element is most commonly found in an ore whose crystals consist of three of this element and eight oxygen atoms.
Though not an alkali metal, this element's carbonate is water-soluble, and this is the lighter of the two elements typically found in MOX fuel.

Penetrative (*) bullets often consist of the depleted variety of this element, which can be extracted from pitchblende or "yellowcake." For ten points, identify this element whose isotope-238 has a very long half-life, and whose atomic symbol is U.
