Specific charge
Proton: charge- 1.6x10^-19 C
mass- 1.67x10^-27 kg
Neutron: charge- 0C
mass- 1.67x10^-27 kg
Electron: charge- -1.6x10^-1b9C
mass- 9.11x10^-31 kg
Specific charge: charge/ mass
charge on an ion= number of electrons gained or lost x 1.6x10^-19 f C
charge on a nucleus = number of protons x 1.6x10^-19 C
mass on a nucleus= number of nucleons x 1.67x10^-27 kg
specific charge of an atom= 0
