Interesting Facts
- Original name of Technetium was Masurium.
- At the time of its discovery it found in sample of Molybdenum.
- Bismuth metal is soluble and reacts with concentrated nitric acid.
- It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

Uses & Benefits
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
- Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
