The first two pieces of information that one should note are the element name and element symbol. Many of the names date back to antiquity (like gold), but newly-discovered elements are actually named by the scientists who discovered them (like Californium), so long as the name is approved...
An example of a deprecated element symbol is Cb for columbium, the former name of the element niobium, or Nb. However, some elements retain their old symbols when they change names. For example, Ag is the element symbol for silver, which was once called argentum. Sources Fontani, Marco; C...
