Rubidium might call it Hahnemann’s remedy, because Hahnemann initiated homeopathy, a hitherto unknown science, which he presented with enthusiasm and a certain impulsive spontaneity, unperturbed by the opinions of other people.
The name has been derived from the Latin word ‘rubidius’ meaning deep red. The Rubidium salts burn with a bright red flame.
It is mildly radioactive. It is used in electric scanners and also in vacuum tubes as it absorbs oxygen very quickly during its oxidisation process. Medical diagnostic techniques make use of its property to accumulate in brain tumours.
