There are many styles of type and many classification systems – defined by their visual characteristics (stroke contrast, serif shape, etc) and their historical development or reference. Here, I've tried to match typefaces over the ages into their main classifications within the element groups on the Periodic Table. Also, except for the Lanthanoids and Actinoids (Glyphic, Script, Blackletter and Graphic faces) and, where possible, in each element group, the typefaces are in roughly in date order from the top to bottom. There are some notable exceptions for aesthetic reasons. For example, Helevtica (1957), had to be Hydrogen!
