Whilst not quite as explosive as Francium, this metallic element still reacts very violently with water and ice, forming the strongest base known today – so strong that it attacks glass!

It was first discovered back in 1860, by Robert Wilhelm Bunsen and Gustav Robert Kirchoff, German chemists, through the spectroscopic analysis of Durkheim mineral water. They named cesium after the blue lines they observed in its spectrum.

However, with the second lowest melting point of all metallic elements cesium has so far been limited in its uses.

But recently it’s been discovered that there’s much more this element can offer. Since it is easily ionized and has a high mass, it’s currently being looked at as a way to propel spacecrafts in the future!
