Which particle in an atom has a positive charge?

In an atom, the particle that has a positive charge is the proton. Protons are located in the nucleus of the atom, alongside neutrons, which have no charge (neutral). Electrons, on the other hand, have a negative charge and are found in the electron cloud surrounding the nucleus. Understanding the role of these particles is fundamental in atomic theory; the protons define the atomic number of an element, which determines its identity and properties. The presence of protons and electrons creates a balance of charges in a neutral atom; the equal number of protons and electrons results in overall electrical neutrality. Thus, knowing that protons carry a positive charge is essential for grasping concepts related to atomic structure and chemical behavior.
