LRA 211 Final Review Study Guide (223/2024) Graded A+ The earliest atomic theory based on an arrangement similar to the solar system is attributed to Rutherford. The three fundamental particles of the atom are the neutron, electron, and proton. The atomic nucleus contains protons and neutrons. The component of the nucleus that has a positive charge and mass is the proton. The electron shell closest to the nucleus is lettered "K". Which of the following is not part of the electromagnetic ...
