Which particle in an atom has no charge?

The neutron is the particle in an atom that possesses no charge. It is found in the nucleus of the atom alongside protons. Protons carry a positive charge, and electrons carry a negative charge; thus, they have distinctly different characteristics from neutrons. The neutral nature of neutrons plays a crucial role in stabilizing the nucleus and allowing for the existence of various isotopes of elements. Understanding the balance of these particles is essential for grasping fundamental concepts in atomic structure and chemistry.
