Detailed explanation-1: -The subatomic particle which has no charge but mass nearly equal to proton is neutron.

Detailed explanation-2: -neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67492749804 × 10−27 kg-marginally greater than that of the proton but 1, 838.68 times greater than that of the electron.

Detailed explanation-3: -Neutrons and protons constitute almost all of an atom’s mass. The third type of stable particle is the electron. Electrons have a negative charge but are extremely small and have a mass only 1/1850 that of a proton or neutron. They are so small that for practical purposes they do not contribute to the mass of the atom.

Detailed explanation-4: -Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists define this amount of mass as one atomic mass unit (amu) or one Dalton. Although similar in mass, protons are positively charged, while neutrons have no charge.

Detailed explanation-5: -Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom’s nucleus as a result of the strong nuclear force.
