1810: Elemental nature of Chlorine discovered by Sir Humphry Davy (1778–1829). 1813: Elemental nature of Iodine discovered by Sir Humphry Davy (1778–1829). 1825: Benzene , the first known aromatic hydrocarbon , isolated and identified by Michael Faraday (1791–1867).
[41] [42] [43] Faraday also determined the composition of the chlorine clathrate hydrate, which had been discovered by Humphry Davy in 1810. [44] [45] Faraday is also responsible for discovering the laws of electrolysis, and for popularising terminology such as anode, cathode, electrode, and ion, terms proposed in large part by William Whewell ...

Sir Humphry Davy is best remembered today for his discoveries of several alkali and alkaline earth metals, as well as contributions to the discoveries of the elemental nature of chlorine and iodine. Ruby Levick was a Welsh sculptor and medallist who had many of her works exhibited at the Royal Academy. [5] [6] [7] [8]
Humphry Davy had discovered a few years earlier that a hot platinum wire lit up in a mixture of coal gas and air. [10]) This release of energy from oxidation of the compounds, without flame, and without change in the platinum itself, was a sign of the catalytic property of platinum investigated later by Johann Döbereiner and other chemists.
