Lead

Atomic symbol: Pb
Atomic number: 82
Atomic mass: 207.2

Appearance: Metallic gray solid at 25°C

Group: 14
Period: 6
Series: Post-transition metals
Block: p
Electron configuration: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p²

Malleable, ductile, and a poor conductor of electricity.

Dense and resistant to corrosion.

Fun Fact! Centuries ago, lead was used in almost everything: paint, piping, and ammunition. Today, due to it being toxic and poisonous, its uses are declining.
