Introduction
Lead is a chemical element with the symbol Pb and atomic number 82. It is a dense, bluish-white metal that is highly malleable and has a low melting point. Lead has been used for thousands of years in various applications, including batteries, pigments, and radiation shielding. In this article, we will explore the properties and applications of lead, and determine which combination of lead's properties and applications is correct.
Properties of Lead
Lead is a soft, malleable metal that has a number of unique properties. Some of its key properties include:
- Soft texture: Lead is a soft metal that can be easily molded and shaped. This property makes it useful for applications where a high degree of flexibility is required.
- Dense structure: Lead is a dense metal with a high density of 11.34 g/cm3. This property makes it useful for applications where a high degree of weight is required.
- Poor electrical conductor: Lead is a poor electrical conductor, meaning that it does not allow electricity to flow easily through it. This property makes it useful for applications where electrical insulation is required.
- Good thermal conductor: Lead is a good thermal conductor, meaning that it allows heat to flow easily through it. This property makes it useful for applications where heat transfer is required.
Applications of Lead
Lead has a number of applications in various industries, including:
- Batteries: Lead is used in the production of lead-acid batteries, which are commonly used in cars and other vehicles. The lead plates in these batteries are used to store electrical energy, which is then released as the battery is discharged.
- Radiation shielding: Lead is used in radiation shielding applications, such as in medical imaging and nuclear reactors. The high density of lead makes it an effective shield against radiation.
- Pigments: Lead is used in the production of pigments, such as lead white and lead chromate. These pigments are used in a variety of applications, including paint and coatings.
- Ammunition: Lead is used in the production of ammunition, such as bullets and shot.
Evaluating the Options
Now that we have explored the properties and applications of lead, let's evaluate the options provided:
- A. Soft texture, poor electrical conductor, used in car batteries: This option is correct, as lead is a soft metal with a poor electrical conductivity, and it is used in the production of lead-acid batteries for cars.
- B. Dense structure, good electrical conductor, used in batteries: This option is incorrect, as lead is a poor electrical conductor, and it is not used in batteries that require good electrical conductivity.
- C. Light weight, used in batteries: This option is incorrect, as lead is a dense metal with a high weight, and it is not used in batteries that require a light weight.
Conclusion
In conclusion, the correct combination of lead's properties and applications is option A: soft texture, poor electrical conductor, used in car batteries. Lead's soft texture and poor electrical conductivity make it an ideal material for use in lead-acid batteries, which are commonly used in cars and other vehicles.
