Rubidium is named after the Latin word rubidius, meaning ‘deepest red.’
It is a group one metal, which makes it soft, highly reactive with water and with a low melting point.
Rubidium helped win a Nobel Prize in Physics in 2001 for the discoverers of Bose-Einstein condensates, says Professor Allan Blackman from the Auckland University of Technology, in episode 70 of Elemental.
The Elemental podcast is celebrating 150 years since the periodic table was first published by Russian chemist Dmitri Mendeleev.
