Ions of uranium
WebUranium is a chemical element with the symbol U and the atomic number 92. There are three naturally occurring isotopes of uranium: uranium-238, the heaviest and most abundant, uranium-235 and uranium-234. Uranium-235 is the only isotope that undergoes fission. This means that it can fragment under the effect of a neutron. Webin / at / on the front line Definitions and Synonyms. phrase. DEFINITIONS 2. 1. doing the hardest or most important work.
