Simple Hexagonal
Tarix
French chemist Georges Urbain successfully separated lutetium from ytterbia in 1907 in Paris.
Austrian scientist Carl Auer von Welsbach and American chemist Charles James also succeeded in isolating lutetium independently in the same year.
Pure lutetium metal was first produced in 1953.
