How did Sir Humphry Davy know potassium was an element?
Potassium was discovered in 1807 by Humphry Davy, who derived it from caustic potash (KOH).It is reasonable to think that at that time he worked in London at the Royal Institution, though he might have lived in his hometown of Penzance, Cornwall[I've digged that out of the following incomplete citations from en.wikipedia]"Davy wrote to Davies Giddy on March 8, 1801 about the offers made by Banks and Thompson, a possible move to London and the promise of funding for Davy's work in galvanism.""By June 1802, after just over a year at the Institution and at the age of 23, Davy was nominated to full lecturer at the Royal Institution of Great Britain. In November 1804 Davy became a Fellow of the Royal Society, over which he would later preside"
