Characteristics:
- Lead is bluish-gray, soft, dense metal that has a bright luster when freshly cut.
- It tarnishes slowly in moist air to form a dull gray coasting. The metal is highly ductile and malleable. Lead is extremely resistant to corrosion and is a poor conductor of electricity.
Applications:
