And the reason they don't is because of the strong nuclear force. In physics, there are four fundamental forces: gravity, the electromagnetic force, the weak force, and the strong force. The strong force is, unsurprisingly, strong. The strong force is the force that holds the nucleus of the atom together, even through other forces want to pull it apart. The electrostatic repulsion (part of the electromagnetic force) between the positive protons in the nucleus is very powerful.
In physics, a force is an interaction between two objects that has the ability to change the motion of one or both of the objects. One of the fundamental forces of the universe is the electric force. This is the force that exists between all charged particles. The electric force is responsible for such diverse phenomena as making your hair stand up on a cold, dry day, creating chemical bonds, and allowing you to see when you turn on a lamp on a dark night.
