Atoms And Electrical Charges

Each atomic particle has an electrical charge. Electrons have a negative (-) charge. Protons have a positive charge. Neutrons have no charge; they are neutral.

In a balanced atom, the number of electrons equals the number of protons. The balance of the opposing negative and positive charges holds the atom together. Like charges repel, unlike charges attract. The positive protons hold the electrons in orbit. Centrifugal force prevents the electrons from moving inward. And, the neutrons cancel the repelling force between protons to hold the atom's core together.
