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

Click For Summary
SUMMARY

An electron possesses a fundamental physical property known as electric charge, specifically a negative charge. Changing the charge of an electron from negative to positive is not possible. However, the charge of a larger body can be altered by adding or removing electrons. The interaction between charges is mutual, meaning both charges exert forces on each other during attraction or repulsion.

PREREQUISITES
  • Understanding of basic physics concepts, particularly electric charge
  • Familiarity with fundamental particles, specifically electrons
  • Knowledge of attraction and repulsion forces in electromagnetism
  • Basic comprehension of how charge can be altered in larger bodies
NEXT STEPS
  • Research the properties of electric charge in quantum mechanics
  • Explore the principles of electromagnetism and Coulomb's law
  • Study the behavior of charged particles in electric fields
  • Learn about particle interactions and fundamental forces in physics
USEFUL FOR

Students of physics, educators explaining electric charge concepts, and anyone interested in the fundamental properties of particles and their interactions.

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:
http://en.wikipedia.org/wiki/Electric_charge

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.
