ETIMOLOGÍA DE LA PALABRA RUBIDIUM
From New Latin, from Latin rubidus dark red, with reference to the two red lines in its spectrum.
QUÉ SIGNIFICA RUBIDIUM EN INGLÉS
Rubidio
El rubidio es un elemento químico con el símbolo Rb y el número atómico 37. El rubidio es un elemento metálico blando, plateado y blanco del grupo de metal alcalino, con una masa atómica de 85.4678. El rubidio elemental es altamente reactivo, con propiedades similares a las de otros metales alcalinos, como la oxidación muy rápida en el aire. El rubidio natural es una mezcla de dos isótopos: 85Rb, el único estable, constituye el 72% del mismo. El 28% restante es el 87Rb ligeramente radiactivo con una vida media de 49 mil millones de años, más de tres veces más que la edad estimada del universo. Los químicos alemanes Robert Bunsen y Gustav Kirchhoff descubrieron rubidium en 1861 por el método recientemente desarrollado de la espectroscopia de la llama. Los compuestos de Rubidium tienen varias aplicaciones químicas y electrónicas. El metal de rubidio se vaporiza fácilmente y tiene una gama de absorción espectral conveniente, haciéndole un blanco frecuente para la manipulación del laser de los átomos. No se sabe que el rubidio sea necesario para ningún organismo vivo. Sin embargo, los iones rubidio son manejados por los organismos vivos de una manera similar a los iones de potasio, siendo absorbidos activamente por las plantas y por las células animales.
definición de rubidium en el diccionario inglés
La definición de rubidio en el diccionario es un elemento radiactivo blando altamente reactivo del grupo de metales alcalinos; el decimosexto elemento más abundante en la corteza terrestre, que se presenta principalmente en polucita, carnalita y lepidolita. Se usa en válvulas electrónicas, fotocélulas y vidrio especial. Símbolo: Rb; número atómico: 37; peso atómico: 85,4678; vida media de 87Rb: 5 × 1011 años; valencia: 1, 2, 3 o 4; densidad relativa: 1.532, 1.475; punto de fusión: 39,48 ° C; punto de ebullición: 688 ° C.
