Gadolinium

Atomic symbol: Gd
Atomic number: 64
Atomic mass: 157.25

Appearance: Silvery white solid at 25°C

Group: N/a Period: 6
Series: Lanthanides
Block: f
Electron configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f⁷ 5d¹ 6s²

Moderately ductile, hard, toxic, and unreactive.

Gadolinium has magnetic properties, making it suitable for use in medical imaging devices, as well as for fluorescent lamp phosphors.

Fun Fact! At low temperatures, gadolinium is more ferromagnetic than iron; at room temperature it is one of few metals to show ferromagnetism too, alongside iron, nickel, and cobalt.
