- Atomic weight - 157.25
- Atomic number - 64
- Electron configuration - 2-8-18-25-9-2
- Oxidation states - +3
- State of matter - solid
- Heavy metal-brittle
- Discovered in 1880 by J.-C.- G. de Marignac and P.-ê Lecoq de Boisbaudran

- Notes:
- Gadolinium has a silvery-white color and is moderately ductile. It becomes
- ferromagnetic below 17 ¯C, and near absolute zero, becomes superconducting. It
- is used for some electronics, high-temperature refratories, and as an alloying
- agent.
