Il rubidio è l'elemento chimico di numero atomico 37 e il suo simbolo è Rb. È un elemento tenero dal colore bianco-argenteo ed appartiene al gruppo dei metalli alcalini. 87Rb, un suo isotopo naturale, è debolmente radioattivo. Come gli altri metalli alcalini, il rubidio è molto reattivo e si infiamma spontaneamente quando viene esposto all'aria.
