Which of the following particles has no charge?

The neutron is the particle that has no charge. It is one of the main components of atomic nuclei, along with protons, which are positively charged. Neutrons contribute to the overall mass of the atom but do not carry any electrical charge, making them electrically neutral. This neutrality plays a crucial role in maintaining the stability of the atomic nucleus, as the presence of uncharged neutrons helps to offset the repulsive forces between the positively charged protons.

In contrast, protons have a positive charge, electrons carry a negative charge, and positrons, being the antimatter counterparts of electrons, have a positive charge as well. Understanding the properties of these particles is fundamental to grasping atomic structure and the behavior of matter in various chemical and physical contexts.
