WebJul 24, 2024 · Electrons exist outside of and surrounding the atom nucleus. Each electron carries one unit of negative charge (1.602 x 10 -19 coulomb) and has a small mass as compared with that of a neutron or proton. Electrons are much less massive than protons or neutrons. The mass of an electron is 9.10938 x 10 -31 kg. WebThe net charge of an atom is determined by the difference in the total number of electrons and protons. If an atom contains more protons than electrons, the net charge is positive and vice versa. Example: An atom containing 5 protons and 3 electrons, has a +2 net charge.
