Initial observations regarding electricity and atomic structure revealed that atoms contain charged particles: electrons, with negative charge, and protons, with positive charge. Additionally, experiments showed that these charged particles interacted with each other and with electric fields.

Thomson's atomic model, proposed in 1904, suggested that atoms resemble a "plum pudding," where negatively charged electrons are embedded within a positively charged sphere, akin to raisins within a pudding, thus implying that atoms are overall electrically neutral.
