Neutrons are classified as particles that possess physical mass but carry no electrical charge. This characteristic is fundamental to their role in atomic structure, where they reside in the nucleus alongside protons. The lack of electrical charge means that neutrons do not interact with electromagnetic forces, distinguishing them from charged particles such as protons and electrons.

Neutrons play a crucial role in the stability of atomic nuclei; their presence helps to offset the repulsive forces between positively charged protons. Additionally, since neutrons are neutral, their interactions are primarily through the strong nuclear force, which is responsible for holding the nucleus together, rather than through electromagnetic interactions.

Understanding neutrons as neutral particles with mass aids in explaining various nuclear phenomena, including nuclear fusion and fission, where their behavior is pivotal. This aspect of neutrons is critical in fields such as nuclear physics and chemistry, as well as in practical applications like nuclear reactors and medical imaging technologies.
