Additional four-fold metal taxonomies of metals were subsequently developed by various authors: From Lavoisier in 1789 to Scott and Kanda in 1962, the classification of metallic elements has reflected changes in scientific thinking. Fittingly, in a cross-discipline fashion, the latter two authors noted that metals in a given class were closely related chemically, electronically, and in the physical characteristics that gave rise to their use in particular alloys (loc. cit.). The relationships within these classes has thus extended to ultimately influencing their utility in various technologies.
