Detailed explanation-1: -The correct answer is Neutron. The neutron is a subatomic particle, symbol n or n⁰, with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.

Detailed explanation-2: -Detailed Solution. Photon is not a part of an atom. They are the subatomic particles with no substructure.

Detailed explanation-3: -A neutron has no charge, whereas a proton has a positive charge that exactly balances the negative charge on an electron.

Detailed explanation-4: -Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Detailed explanation-5: -Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).
