El uranio es un elemento químico metálico de color plateado-grisáceo de la serie de los actínidos, su símbolo químico es U y su número atómico es 92. Por ello posee 92 protones y 92 electrones, con una valencia de 6. Su núcleo puede contener entre 140 y 146 neutrones, sus isótopos más abundantes son el 238U que posee 146 neutrones y el 235U con 143 neutrones. El uranio tiene el mayor peso atómico de entre todos los elementos que se encuentran en la naturaleza. El uranio es aproximadamente un 70 % más denso que el plomo, aunque menos denso que el oro o el tungsteno. Es levemente radiactivo. Fue descubierto como óxido en 1789 por M. H. Klaproth que lo llamó así en el honor del planeta Urano que acababa de ser descubierto en 1781.
