Which statement is true about neutrons?

Neutrons are subatomic particles found in the nucleus of an atom, and they are characterized by having no electrical charge. This means they are neutral, which is critical for maintaining the stability of the nucleus when paired with positively charged protons. Their presence helps to reduce the electrostatic repulsion between protons, as protons repel each other due to their positive charges.

This neutral charge also plays a significant role in various nuclear reactions and is essential for understanding concepts such as isotopes, which are variants of elements that have the same number of protons but different numbers of neutrons. The other statements incorrectly suggest that neutrons possess a charge, which is fundamental to the student's understanding of atomic structure.
