How do positive protons and negative electrons keep an atom together?

An atom is held together by the attractive electric force between its constituent particles.12

The nucleus, located at the center of the atom, contains protons that carry a positive electrical charge. Surrounding this nucleus is a cloud of electrons, which are negatively charged. Because opposite electric charges attract one another, this force acts similarly to the way gravity keeps planets in orbit, binding the negative electrons to the positive nucleus.132

In a neutral atom, the number of protons and electrons is equal, balancing the positive and negative charges. While the nucleus itself contains protons that repel each other due to their identical positive charges, it remains stable because of the strong force, a powerful, short-range force that overcomes this electrical repulsion to hold the nucleus together.435
