|sm|, |eu|, |gd|, and |tb|
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 |y| (large chunk), |yb| (in ampoule), |tb| (brassy pieces), |er| (silvery pieces). Also included are small pieces of dull, slightly oxidized |ho|, which takes the name of Stockholm, Sweden.
Small chunk of mostly shiny Terbium metal. |tb| should not be confused with |er|!
