Interesting Facts
- 223 Francium has the longest half life at 21.8.
- Francium metal is produced by alpha decay in 227Actinium 227.
- Plutonium metal if obtain from ores of uranium metal.
- Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
Sources
