By: TB 7.4 #21 Terbium (Tb)

Basic Information Atomic number = 65 Symbol = Tb Density = 8.229 g/cc Melting Point = 1633.15 K Boiling Point = 3314.15 K Number of Protons and Electrons: 65 Number of Neutrons: 94

What is Terbium? Terbium is ductile, soft and rare It is metallic The color is silver- grey It contains many minerals (eg. gadolinite, monazite, xenotime, etc)

What is Terbium? Has a hexogonal shape Mostly a negative atomic structure 65 positive and 94 negative Terbium is not considered as hazardous towards the environment or animals.

How Terbium is named? Discovered by Carl Gustaf Mosander Discovered in Sweden in 1843 Some people believed that Terbium is named after the 3 major components

What Is It Used For? Terbium Is used for colored television tubes Terbium Is used for X-rays Terbium is used for Lasers Terbium is used in Alloys
