Uses & Benefits
- It is a liquid metal at room temperature, but it is a toxic heavy metal and hence many uses of mercury are under review or phased out.
- It is manly used as a catalysts in chemical industry.
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
