Terbium Element Cube SR-71 Titanium This unique composition gives themTerbium's atomic number is 65 and its symbol is Tb. Terbiums physical properties resemble those of tin in that it is malleable, ductile, and fairly soft. However, that is where the similarities end. It is never found in nature as a pure element, rather, it is harvested from minerals. Terbium reacts slowly in water to produce hydrogen gas and is mildly toxic. Its most common industrial use is to produce solid state electronics.
