The charge to mass ratio of an electron is approximately -1.76 x 10^11 coulombs per kilogram. This means that electrons have a very small mass compared to their charge. This value was first measured by J.J. Thomson in his experiments with cathode rays.
The electron has a charge of -1; but the electron has a mass.
The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
It is a simple ratio charge/mass or e/m .
The mass of an electron is much smaller than the mass of a proton. An electron has a charge of -1, while a proton has a charge of +1.
The ratio of the specific charge of an electron to that of a positron is 1:1. Both the electron and positron have the same magnitude of charge but opposite in sign, with the electron being negative and the positron being positive.
