Did You Know?
It was discovered using spectroscopy by Robert Bunsen and Gustav Kirchhoff, who noticed a unique set of deep red lines in the spectrum of a mineral sample. The name comes from the Latin 'rubidus' for 'deepest red'.
Rubidium is used in some of the world's most accurate atomic clocks.
It is so reactive that it can ignite spontaneously in air and reacts violently with water.
It melts at a very low temperature of 39.3 °C (102.7 °F), meaning it would be a liquid on a very hot summer day.
The human body tends to treat rubidium ions as if they were potassium ions, so it can become widely distributed in the body if ingested.
