Out of the following given choices;
(1) An electron and a proton both have a charge of +1.
(2) An electron and a proton both have a charge of —1.
(3) An electron has a charge of +1, and a proton has a charge of -1.
(4) An electron has a charge of —I and a proton have a charge of +1.
The answer is 4. Protons are sub-atomic particles that are found in the nucleus of the atom, while the electron is found in the atomic orbitals that revolve around the nucleus in planetary fashion. An electron has -1.6*10^-19 Coulombs while a proton 1.6*10^-19 Coulombs. The positive charge of the nucleus is what attracts and keeps the negatively charged electrons around the nucleus.
