Facts about lead
Here are a few interesting facts about lead element.
- The earth’s crust has around 114 ppm (by weight) of lead.
- Lead has been discovered since ancient times.
- More lead in the human body can affect the kidneys, heart, intestines, as well as nervous system.
- Lead sulfide (PbS) is the main ore of lead and majority of lead is obtained from this ore.
Properties of lead
Here is a list of some physical properties and chemical properties of lead.
Physical properties of lead
- Lead has a silvery gray metallic appearance.
- Lead is not a good conductor of electricity.
- Lead is malleable and ductile metal.
- Lead has many isotopes and out of those isotopes, the most abundant isotope is 208Pb.
- Lead has FCC crystal structure.
- The melting point and boiling point of lead is 600.6 K and 2022 K respectively.
Chemical properties of lead
- Lead reacts with the atmospheric oxygen and forms a gray oxide layer on it.
- The most common oxidation states of lead are +2 and +4.
- Lead has an electronegativity of 2.33 on the pauling’s scale.
- The electron configuration of lead is [Xe] 4f14 5d10 6s2 6p2. This shows that the last electron enters the p-orbital, and hence it is a p-block element.
Uses of lead
Here are some uses of the lead element.
- Majority of lead is used in manufacturing of lead batteries.
- Lead is used in manufacturing of bullets as well as radiation shields.
- Lead metal was used in plumbing works. But now its use has been stopped due to the toxicity of lead.
- Lead is also used in the covering materials used for cables.
