After studying the phenomenon of electrolysis in 1874 the Anglo Irish physicist G Johnstone Stoney suggested that there existed a single definite quantity of electricity He was able to estimate the value of the charge e of a monovalent ion by means of Faraday s laws of electrolysis 10 This means that chemistry is part of the definitio if the electron The value of charge was equated to faradays laws of electrolysis There should be an section in the electron article on chemistry And if your going to mention obscure virtual electrons why not mention chrystal fields because that is fundamental to chemistry If your going to mention quantum physics why ca nt you mention quantum chemsitry because I think chemistry is just as important to physics if not more important And I think there should be a section on electrolysis
