Four chemical elements were named after the town of Ytterby, Sweden, where many rare-earth elements were discovered from the ores mined there. In this photo is Yttrium (large chunk), Ytterbium (in ampoule), Terbium (brassy pieces), Erbium (silvery pieces). Also included are small pieces of dull, slightly oxidized Holmium , which takes the name of Stockholm, Sweden.
Small chunk of mostly shiny Terbium metal. Terbium should not be confused with Erbium !
