What type of charge do oppositely charged particles exhibit when they interact?

Oppositely charged particles, such as protons and electrons, exhibit a fundamental electric force that causes them to attract each other. This attraction arises from the nature of electric charges; opposite charges exert a force that pulls them closer together, while like charges push each other away.

When these particles interact, the attractive force can lead to various phenomena, including the formation of atoms, where negatively charged electrons are bound to positively charged protons in the nucleus. This interaction is essential in many areas of physics and chemistry, influencing how matter is structured at the atomic level.

The attraction between opposite charges can be observed in everyday situations as well, such as when a balloon is rubbed on hair and then sticks to a wall or picks up small pieces of paper.
