Physical Properties: Terbium is a silvery- white rare earth metal that is malleable, ductile and soft enough to be scratched with a knife. It is relatively stable in air as compared to other lanthanides.
Chemical Properties: Terbium metal reacts with all the halogens, forming white trihalides. Terbium also dissolves in diluted sulfuric acid to form solutions containing the pale pink Terbium ions.
