positive
Inside the atom, two types of subatomic particles have electric charge: electrons, which have an electric charge of -1, and protons, which have an opposite but equal electric charge of +1. The model of an atom in the Figure below shows both types of charged particles. Protons are found inside the nucleus at the center of the atom, and they give the nucleus a positive charge. There are also neutrons in the nucleus, but they have no electric charge. Negative electrons stay in the area surrounding the positive nucleus because of the electromagnetic force of attraction between them.
