A hydrogen nucleus is simply a proton, which has equal and opposite charge to an electron.
Specific charge = charge / mass, so the value by which you divide will be vastly different between a proton and an electron.

Specific charge is charge/mass
They both have the same charge, just opposite, but the proton (hydrogen nucleus) has a mass 2000x that of an electron, so you can see that the s.c. of an electron is going to be 2000x larger.Last edited by W. A. Mozart; 17-09-2016 at 16:30.
