Hofmann's chemical models. Artwork showing how early chemical models were used to demonstrate the formation of molecules, in this case ammonia (NH3).
Hofmann's chemical models. Artwork showing how early chemical models were used to demonstrate the formation of molecules, in this case ammonia (NH3). This demonstration was performed by the German chemist August Wilhelm von Hofmann (1818-1892) when he gave a lecture to the Royal Institution in London, England, on 7 April 1865. The title was 'On the Combining Power of Atoms', and these artworks were later published in the journal 'Proceedings of the Royal Institution' (volume 4, 1866, ).
