Here's why:

* Atoms are made of protons, neutrons, and electrons.

* Protons have a positive charge.

* Electrons have a negative charge.

* Neutrons are neutral, meaning they have no charge.

The neutrality of neutrons is crucial for the stability of atoms. The positive charge of protons and the negative charge of electrons balance each other out, and the neutrons act as "glue" holding the nucleus together.
