Uses & Benefits
- Actinium metal has a great source of alpha rays but it is hardly used outside research purpose.
- 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.
