Maybe this will help:

http://en.wikipedia.org/wiki/Elementary_charge

The electron carries a 'negative' charge whilst the proton carries a 'positive' charge.  They are equal in magnitude but opposite in polarity.

and

http://en.wikipedia.org/wiki/Electron

The electron and proton are usually associated with the structure of the atom where the number of electrons is associated with a proton to equal out the total charge on the atom.
