Rhodium Element Project

Properties: Rhodium metal is silvery-white. When exposed to red heat, the metal slowly changes in air to the sesquioxide. At higher temperatures it converts back to its elemental form . Rhodium has a higher melting point and lower density than platinum. The melting point of rhodium is 1966 +/-3°C, boiling point 3727 +/-100°C, specific gravity 12.41 (20°C), with a valence of 2, 3, 4, 5, and 6.
