What does it mean that an electron has a negative charge?

[Moris526]

Hi.
What is a ¨charge¨ ? What does it mean that an electron has a negative charge?

What is modified in particle when it changes charge, if posible.?

When two charges atract , is one that pulls the other or both pull each other?

thanks

A charge is just a fundamental physical property. It's hard to explain it here, you might want to read this:

On whether it's possible to change, for example the charge of an electron from - to +, I have to say I do not know for sure, but it does not appear possible.

On the other hand, if by "particle" you are not referring to the fundamental unit of charge (the electron) but some body, then the charge on that body may be changed by adding or removing electrons. But it appears that your question is more likely the former.

Attraction and repulsion of charges is mutual. Both charges experience the force.

Hello,

I can provide an explanation for your questions. A charge is a fundamental property of matter that describes the interaction between particles. It is a measure of the amount of electric force that a particle experiences. An electron is a subatomic particle that orbits the nucleus of an atom and has a negative charge. This means that it has an excess of negative charge compared to positive charge.

When a particle changes its charge, it means that there has been a transfer of electrons between particles. This can happen through various processes such as friction, contact, or chemical reactions. The modification in the particle depends on the type of charge it acquires. For example, if a particle gains a positive charge, it means that it has gained electrons and now has more protons than electrons.

When two charges attract, it means that they are exerting an electric force on each other. In the case of an electron and a positively charged particle, the electron will be pulled towards the positive charge. However, both particles are also pulling on each other due to their opposite charges. This is known as the Coulomb force and is described by the law of electrostatics.

I hope this helps to clarify the concept of charge and its role in explaining the behavior of particles. Let me know if you have any further questions. Thank you.
