우라늄 개요

Investigation of uranium salts led to the recognition of radioactivity itself, and the element remains the foundation of civil nuclear power. Uranium carries atomic number 92 and a relative atomic mass of 238.03, the highest of any element found in quantity in nature. Its configuration [Rn] 5f3 6d1 7s2 places it in the f-block of period 7, and its Pauling electronegativity is 1.38. The metal is dense and solid at standard temperature and pressure. Its principal application is as reactor fuel, where fission of the lighter isotope releases the energy that drives commercial nuclear generation. Chemically, uranium is a reactive actinide whose oxide chemistry governs both how the ore is processed and how spent fuel behaves in storage.
