ResourceOn This Day - Mar 31 : Robert Bunsen was born
Bunsen pioneered spectroscopy using his famous invention of the Bunsen burner to produce the clean flame necessary to heat substances and measure the wavelengths of light they emit. Using this method, Bunsen discovered caesium (Cs) and rubidium (Rb).

ResourceOn This Day - Mar 23 : First noble gas reaction
Noble gases were thought to be completely inert, but English chemist Neil Bartlett observed that mixing platinum hexafluoride with xenon formed the yellow solid xenon hexafluoroplatinate. This led to many more discoveries of noble gas compounds.

ResourceOn This Day - Jan 18 : Edward Frankland was born
Frankland introduced the theory of valence when he realised that atoms can only form a certain number of bonds to other atoms. He also co-discovered helium (He), pioneered organometallic chemistry, and was a leader in the field of water purification.
