Physics Course/Particles


Long time ago , Newton proposed that all matter consist of particles . Then John Dalton experiment points out that all matter made up from smallest particles of matter that still has matter's property when undergo a chemical reaction called Atom . Later on , J J Thomson experiment point out that Atom can be decomposed into smaller Electric Charged Carrying Particles called Charged Particles .

Electric Charged Particles

Charged particles are sub atomic particles . There are three kind of Charged Particles namely Electron , Proton and Neutron. Electron has a negative charge . Proton has a positive charge and Neutron has no charge or neutral in charge . These charged particles cannot be divided further . The characteristic of these three charged particles are shown below
