Confusing question about the movement of electrons

In summary, Dave explains that electrons move from high to low potential in a battery due to the separation of negative and positive charges, which creates a potential difference between the terminals.

Hi guys
Do electrons move from high to low potential or from low to high potential I think the first one ia right because when electrons are attracted to the negative terminal they have maximum potential energy

Hi Ahmad

electrons are not attracted to the negative terminal

specifically, are you referring to a battery or some other type of power supply ?

the basics of a battery are that the chemical reaction in the battery/cell causes the separation of free electrons from atoms so that we get an accumulation of electrons (negative charges) at one end of the cell ( the negative terminal) and an accumulation of ions (positive charges) at the other end of cell ( the positive terminal)

This separation of negative and positive charges produces a potential difference between the terminals

Does that help ?

cheers
Dave
 

FAQ: Confusing question about the movement of electrons

1. What is the difference between electrons and protons?

Electrons are negatively charged particles that orbit the nucleus of an atom, while protons are positively charged particles that make up the nucleus. Electrons are much smaller in size and mass compared to protons.

2. How do electrons move within an atom?

Electrons move in specific energy levels or orbitals around the nucleus of an atom. These energy levels determine the distance of the electron from the nucleus and its energy state. Electrons can also move between energy levels by absorbing or releasing energy.

3. Can electrons move from one atom to another?

Yes, electrons can move from one atom to another through a process called electron transfer. This typically happens during chemical reactions when atoms share, gain, or lose electrons to form new compounds.

4. What is the role of electrons in electricity?

Electrons play a crucial role in the flow of electricity. When electrons move from one atom to another, they create an electric current. This movement of electrons is what powers electrical devices and circuits.

5. Do electrons always move in the same direction?

No, electrons can move in either direction within an atom, depending on the circumstances. In terms of electricity, electrons typically move from the negative terminal to the positive terminal, but they can also flow in the opposite direction under certain conditions.
