Which particle has a positive charge?

The proton is the particle that carries a positive charge. In atomic structure, protons are found within the nucleus of an atom, alongside neutrons, which have no charge. The presence of protons is critical, as their positive charge plays a key role in the structure of atoms, helping to balance the negative charge of electrons, which orbit the nucleus. The interaction between these charged particles is fundamental to the stability of matter and the formation of chemical bonds. Understanding the roles of protons and their positive charge is essential in fields such as chemistry and physics, as it influences atomic behavior and interactions.
