Not for its eyes (it's only an element!) but less romantically for the appearance of its emission spectrum in the spectroscope. Caesium was discovered in 1860 by Robert Bunsen (he of the burner fame) ...

And what is the chemical symbol for aluminium ... The melting points then get gradually lower, with the element caesium four places down having a melting point of 28°C. A hypothesis is a ...

Pauling's electronegativity scale, the most widely used and found in every chemistry textbook, ranges from 0.7 for cesium to 4.0 for fluorine. The higher an element's electronegativity, the stronger ...

Russian, Chinese, Japanese, and Italian scientists have synthesized two polyhydrides – cesium heptahydride (CsH7) and rubidium nonahydride (RbH9) – for the chemical storage of hydrogen.

You're listening to Chemistry in its element brought to you by Chemistry World, the magazine of the Royal Society of Chemistry. In a way, the story of rubidium starts in 1859 when the German chemists ...
