From Glyph to Element Symbol – A Story of Names
CHIMIA, 2019 When I write the symbol Fe, all scientists know that I am talking about iron. Today's chemists use element symbols in formulae without thinking where they came from. This article looks at the history of element symbols and why we use the ones we
