Wooden Atomic Models used by John Dalton, 1800-1844

That is precisely what John Dalton did. Much of the Dalton Atomic Model has been disproven, but he is still considered the man who laid the foundation for the atomic theory we celebrate today. Before we dive into the Dalton atomic model, let’s take a brief overview of the atomic theory that had been established before it. Natural philosopher John Dalton- as well as a birth date for the theory: Dalton’s September 6, 1803, entry in his laboratory notebook.

Dalton became secretary of the Manchester Literary and Philosophical Society in 1800 and a Fellow. 10 The earliest, inductivist, account saw Dalton’s 1804 work on marsh gas as the crucial event. See Thomson, T., The History of Chemistry (London, 1830 – 1831), ii, 291. Google Scholar Recognizing the inadequacies of Thomson’s account, Meldrum sought in his 1909-11 papers to remodel the inductivist version, basing it on Dalton’s 1803 work on the nitrogen oxides. • Much of Dalton’s written work, collected by the Manchester Literary and Philosophical Society, was damaged during bombing on 24 December 1940.
