It is negative charge. The amount of the charge is -1.6x10-19 coulomb. Mass of electron is 9.11x10-31 kg or 0.00054859 a.m.u. Since atom has equal number of electrons and protons and they have equal and opposite charges hence they cancel their effect and atom becomes neutral. It is 1836 times lighter than proton.
