Lead is a heavy metal that is used in construction and industry. It is also used for a variety of other applications. It has been in use since ancient times.
Lead is a member of Group 14 of the periodic table. Lead is found in the Earth’s crust in almost the same abundance as tin. The melting point of lead is 328 degC.
Lead is a very durable and corrosion-resistant metal. It is used for shielding from radiation. However, it is not a good conductor of electricity. If lead is melted, it can cause a fire. You can prevent this from happening by using proper safety gear and precautions.
Lead is highly toxic in small amounts. It can be poisonous when poured into food. Therefore, it should never be reused for food preparation.
While lead is used in many applications, it is not widely used as a structural material. It has low tensile strength and fatigue strength.
Because of its high density and high atomic number, it has a low melting point. Lead has been considered the oldest metal known to man. During the Ancient Roman period, lead was used in water pipes.
The atomic number of lead is 82. Lead compounds are usually in the +2 oxidation state. When lead is exposed to air, it tarnishes to a grayish color.
Lead is a member of Group 14. In the Periodic Table, it is placed between the elements tin and sulfide.
