Which particle in an atom has no charge?

The neutron is the particle within an atom that carries no charge. It is found in the nucleus alongside protons, which are positively charged. The absence of charge in neutrons contributes to the overall stability of the atomic nucleus, as they help to balance the repulsive forces between the positively charged protons. Understanding the role of neutrons is crucial in grasping atomic structure and the behavior of elements.

Electrons, on the other hand, are negatively charged particles that orbit the nucleus, and protons are positively charged particles located in the nucleus. An ion refers to an atom that has lost or gained electrons, resulting in a net charge, either positive or negative. Therefore, the neutron stands out as the only neutral particle in this context.
