Lutetium(Lu) Element

Pure metal lutetium has been isolated only in recent years and is one of the more difficult to prepare. It can be prepared by the reduction of anhydrous LuCl₃ or LuF₃ by an alkali or alkaline earth metal. The metal is silvery white and relatively stable in air. It is the hardest and the densest of the lanthanides.
