# Electrostatic: Electron Transfer & Conductivity

• Tam Le
In summary: Static electricity is generated when two objects with different electrical charges are brought into close contact. The object with the higher charge will attract the electrons from the object with the lower charge.

If you rub two electrically neutral pieces of insulation together, one piece becomes charged and the other piece becomes oppositely charged.

Does this transfer of electron depend merely on the electron affinities of the two pieces, or does the conductivity of the two insulations play a part?

I imagine a poor insulator (high conductivity) to have a lower electron affinity; it wants to move/get rid of its electrons. Likewise, I imagine a good insulator (low conductivity) to have a higher electron affinity; it wants to hold onto its electrons.

After reading your link and others, I think I cleared the confusion: I thought that since conductors are good at moving charges throughout them, they must also be good at transferring their charges. Hence, I thought that if I rubbed two different, electrically neutral, nonpolarized materials together, the better conducting material would conduct its electrons to the poorer conducting material, thus eliminating the electron affinity explanation. However, I completely forgot to factor in that nonpolarized and electrically neutral part, which would interfere with charge transfer. I basically attempted to explain charging by friction with charging by induction and conduction.

I also thought that electron affinity was somehow inversely proportional to conductivity. But, after not much research, I found that was not the case: Au and Ag, for example, have both high electron affinity and high conductivity.

To conclude, I should have done more research before posting this question; I admit my ignorance .

But, feel free to ask about anything in your research that you have a problem understanding. We love getting questions. Demonstrate a little effort and you will get responses from people who like to help. It just that it is very difficult to explain things from the very very beginning.

We're all ignorant, but on different subjects.

## What is electrostatics?

Electrostatics is the study of electrically charged particles, specifically the forces and interactions between them. This includes the study of electric fields, electric potential, and the movement of charged particles.

## What is electron transfer?

Electron transfer is the movement of electrons from one atom or molecule to another. This can occur through various mechanisms such as conduction, induction, or radiation.

## How does electron transfer affect conductivity?

Electron transfer is essential for conductivity as it allows for the movement of charged particles, which is necessary for the flow of electrical current. Without the transfer of electrons, a material would not be able to conduct electricity.

## What factors affect electron transfer and conductivity?

The conductivity of a material is influenced by various factors, such as the number of free electrons, the type of material, temperature, and the presence of impurities. These factors can also impact the rate of electron transfer.

## What are some real-world applications of electron transfer and conductivity?

Electron transfer and conductivity have numerous practical applications, including the functioning of electronic devices, such as computers and smartphones, the operation of power grids, and the production of metals in metallurgy. They also play a crucial role in biological processes, such as nerve signaling and muscle contractions.
