Question about conductivity and metal bonds

In summary, the conversation discusses the effects of a strong electric field on a metal sphere and a small metal object placed within it. The displacement of electrons within the metal due to the electric field raises questions about the impact on metal bonds and overall strength. The person asking the question is seeking serious answers with a scientific basis. It is also mentioned that only valence electrons may be mobile in the presence of an electric field.

Hello everybody. I would like to ask the following:
Imagine a source of strong electric filed. For example a positively charged metal sphere. Then we put a small (relatively to the source of the electric field) metal object in the electric field. Electron inside the metal move in such way, that they compensate the electric field inside the metal. The final picture is that some of the electrons are located at the one end of the metal. So, my question is, how that displacement of the electrons affect metal bonds in the metal. If the electric field is stronger do more electron displace and if so, what keep metal atoms together?
The question may look extremely stupid, but it is not. I request only serious answers with scientific foundation. As addition I am curious which electrons are mobile and can move freely at the presence of electric field, only valence electrons or other too? Does the electric filed affect metal strength and so on.

Thank you for your attention.

If you are suggesting that the strength would be affected then you would need to consider the total number of electrons involved in the bonding and the number of electrons which would actually be displaced by the existence of an external field. I think the effect would be undetectable.
 

1. What is conductivity?

Conductivity is the measure of a material's ability to conduct electricity. It is the result of the flow of electrically charged particles, called electrons, through a material.

2. How do metal bonds affect conductivity?

Metal bonds, also known as metallic bonds, have a strong influence on conductivity. These bonds are formed when atoms share their outermost electrons, creating a "sea" of free electrons that can move freely throughout the metal. This allows for easy flow of electricity, making metals good conductors.

3. What factors affect metal conductivity?

Several factors can affect the conductivity of metals, including temperature, impurities, and crystal structure. High temperatures can increase the vibrations of atoms, which can impede the flow of electrons, reducing conductivity. Impurities can also disrupt the orderly flow of electrons, decreasing conductivity. The crystal structure of a metal also plays a role, as some structures may have higher conductivity than others.

4. How does the arrangement of metal atoms influence conductivity?

The arrangement of metal atoms in a crystal lattice can greatly impact conductivity. Metals with a more compact and orderly structure tend to have higher conductivity, as the electrons have a more direct path to travel through the material. In contrast, metals with a less organized structure may have lower conductivity due to more obstacles for the electrons to navigate.

5. What are some common applications of metals with high conductivity?

Metals with high conductivity, such as copper, aluminum, and silver, have many practical applications. They are commonly used in electrical wiring, circuit boards, and other electronic components. They are also used in power generation and transmission, as well as in various industries for their ability to efficiently conduct heat and electricity.
