Cerium

Atomic symbol: Ce
Atomic number: 58
Atomic mass: 140.12

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 4f¹ 5d¹ 6s²

Similarly to lanthanum, cerium is a soft, ductile and malleable metal.

Cerium is a lot easier to extract than lanthanum and is the most common lanthanide.

Fun Fact! Despite having no known biological function, the human body contains small amounts of cerium in the bones, blood, and tissues.
