QUÉ SIGNIFICA URANIUM EN INGLÉS
Uranio
El uranio es un elemento químico metálico blanco plateado en la serie de actínidos de la tabla periódica, con el símbolo U y el número atómico 92. Un átomo de uranio tiene 92 protones y 92 electrones, de los cuales 6 son electrones de valencia. El uranio es débilmente radioactivo porque todos sus isótopos son inestables. Los isótopos más comunes del uranio son uranio-238 y uranio-235. El uranio tiene el segundo peso atómico más alto de los elementos primordialmente presentes, más ligero que el plutonio. Su densidad es aproximadamente 70% más alta que la del plomo, pero no tan densa como el oro o el tungsteno. Se produce naturalmente en bajas concentraciones de unas pocas partes por millón de suelo, roca y agua, y se extrae comercialmente de minerales que contienen uranio, como la uraninita. En la naturaleza, el uranio se encuentra como uranio-238, uranio-235, y una cantidad muy pequeña de uranio-234. El uranio se desintegra lentamente al emitir una partícula alfa. La vida media del uranio-238 es de unos 4,47 millones de años y la del uranio-235 es de 704 millones de años, lo que los hace útiles para fechar la edad de la Tierra. Muchos usos contemporáneos del uranio explotan sus propiedades nucleares únicas.
