Rubidium upptäcktes första gången av Robert Bunsen och Gustav Kirchhoff i Heidelberg 1861 genom att använda spektroskopi. På grund av de ljusa röda linjerna i strålningen valde de ett latinskt namn, rubidus, som har betydelsen mörkröd. Bunsen var även den förste att framställa metalliskt rubidium, vilket han gjorde genom reduktion ...
