Forces Around Atoms Summary

ATOM AND ITS FORCES Basic Electrical Theory Summary The important information contained in this chapter is summarized below. Forces Around Atoms Summary Electrostatic Force - force that holds an electron in orbit around a nucleus Electrostatic Field - force acting between charged objects that causes them to repel or attract Potential Difference - measures how large the electrostatic force is between two charged objects. According to Coulomb’s Law, charged bodies attract or repel each other with a force that is directly proportional to the product of their charges and is inversely proportional to the square of the distance between them. Electromotive Force (EMF) - sum of the potential differences of all charged particles in an electrostatic field Ion Charge - dependent on the loss or gain of free electrons (if an atom gains an electron - negative ion charge; if an atom loses an electron - positive ion charge) ES-01 Page 8 Rev. 0
