ETIMOLOGÍA DE LA PALABRA AMERICIUM
From America (because it was discovered at Berkeley, California) + -ium.
QUÉ SIGNIFICA AMERICIUM EN INGLÉS
Americio
El americio es un elemento químico transuránico radiactivo que tiene el símbolo Am y número atómico 95. Este miembro de la serie de actínidos se encuentra en la tabla periódica bajo el elemento de lantánido europio, y por lo tanto por analogía fue nombrado después de otro continente, América. El americio fue producido por primera vez en 1944 por el grupo de Glenn T. Seaborg en la Universidad de California, Berkeley. Aunque es el tercer elemento en la serie transuránica, fue descubierto cuarto, después del curio más pesado. El descubrimiento se mantuvo en secreto y sólo se dio a conocer al público en noviembre de 1945. La mayoría del americio se produce bombardeando uranio o plutonio con neutrones en reactores nucleares - una tonelada de combustible nuclear gastado contiene alrededor de 100 gramos de americio. Es ampliamente utilizado en los detectores de humo comerciales de cámara de ionización, así como en fuentes de neutrones y medidores industriales. Para el isótopo 242mAm se han propuesto varias aplicaciones inusuales, como una batería nuclear o un combustible para las naves espaciales con propulsión nuclear, pero todavía están obstaculizadas por la escasez y el alto precio de este isómero nuclear. El americio es un metal radioactivo relativamente blando con aspecto plateado.
definición de americium en el diccionario inglés
La definición de americio en el diccionario es un elemento transuránico metálico blanco producido artificialmente a partir de plutonio. Se usa como una fuente de partículas alfa.
