The world is made up of different and complex matter. This “matter” is made up of trillions of atoms, and each atom has protons, neutrons, and electrons orbiting around the atom. By knowing how many electrons an atom has, scientist can find out what the specific charge is of the atom. This charge is known as an electrical charge or force. These electrical forces vary in charges; positive, negative, and neutral. These charges have similar principles to the charges of a magnet. Like charges repel each other, unlike charges attract each other, and neutral charges attract both positive and negative charges.
