ATOM AND ITS FORCESBasic Electrical TheorySummaryThe important information contained in this chapter is summarized below.Forces Around Atoms SummaryElectrostatic Force - force that holds an electron in orbit around a nucleusElectrostatic Field - force acting between charged objects that causesthem to repel or attractPotential Difference - measures how large the electrostatic force isbetween two charged objects. According to Coulomb’s Law, chargedbodies attract or repel each other with a force that is directly proportionalto the product of their charges and is inversely proportional to the squareof the distance between them.Electromotive Force (EMF) - sum of the potential differences of allcharged particles in an electrostatic fieldIon Charge - dependent on the loss or gain of free electrons (if an atomgains an electron - negative ion charge; if an atom loses an electron -positive ion charge)ES-01 Page 8 Rev. 0
