Atomic Structure

Proton and nucleon number

Isotope

Same element, same proton number, different nucleon number

Electric field

Charge: greater the charge, greater the extent of deflection

Mass: greater the mass, the smaller the extent of deflection

Proton VS Electron: electron deflects to a larger extent than proton as electron has a smaller mass

Proton —> negative side, Electron —> positive side, Neutron —> middle
