Contribution to the Development of the Atomic Concept
As a young man, Davy became the Director of Thomas Beddoes' Pneumatic Institute in Bristol. One of Davy's first scientific accomplishments was his discovery of the physiological effects of nitrous oxide, which became known as "laughing gas".  As part of this work he also characterized the various oxides of nitrogen with great care. After his appointment as a lecturer at the Royal Institution in London he used a voltaic pile (the first true battery developed by Alessandro Volta) to electrolyze various molten metal oxides to isolate potassium and sodium (1807) and then calcium, barium, strontium, and magnesium (1808).  He also named aluminum, boron, chlorine, and iodine.  In 1815 Davy invented his miner's safety helmet. The lamp of this safety helmet would burn safely and emit light even when there was an explosive mixture of methane and air present.
