The electron, denoted e- is a fundamental particle with negative electric charge that is found arranged in quantum mechanical orbits about neutral atoms. The electron is a lepton, and therefore has lepton number 1. The antiparticle of the electron is called the positron.
The electron mass is 9.1095*10^31 kg, and the electron charge -e , where e=1.6022*10^19 C.
I gleened this information by googling "electron charge"
