GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -(iii) Neutrons are electrically neutral particles which have the same mass as a proton. These together with protons are called nucleons and are present inside the nucleus.

Detailed explanation-3: -Miller, a UW physics professor, has found that the neutron has a negative charge both in its inner core and its outer edge, with a positive charge sandwiched in between to make the particle electrically neutral.
