Which particles in the atomic nucleus are neutral?

Neutrons are the particles in the atomic nucleus that are neutral, meaning they carry no electrical charge. This neutrality is crucial for the stability of the nucleus. While protons, which are also present in the nucleus, carry a positive charge, neutrons help to balance the nuclear forces that hold the nucleus together, countering the repulsive force between positively charged protons. Electrons, on the other hand, are found outside the nucleus and have a negative charge. Atoms themselves are composed of protons, neutrons, and electrons, but when considering the particles specifically in the nucleus, only neutrons are neutral.
