Which particle in an atom has a positive charge?

In an atom, the proton is the particle that carries a positive charge. Protons are found in the nucleus of the atom, which is the dense center that also contains neutrons, which have no charge. The positive charge of protons plays a crucial role in determining the atom's overall charge and its interaction with other particles.

Electrons, on the other hand, are negatively charged and orbit the nucleus, balancing the positive charge of protons to create a neutral atom. Neutrons do not have any charge and therefore do not contribute to the charge of the atom. While the nucleus refers to the central part of the atom that houses protons and neutrons, it is the protons specifically that impart a positive charge to the atom. This is why identifying protons as the positively charged particles is key to understanding atomic structure and behavior.
