Interesting Facts
- Original name of Technetium was Masurium.
- At the time of its discovery it found in sample of Molybdenum.
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses & Benefits
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
