GENERAL KNOWLEDGE

Detailed explanation-1: -The neutron is a neutral particle, which is stable only in the confines of the nucleus of the atom. Outside the nucleus the neutron decays with a mean lifetime of about 15 min. Its mass, like that of the proton, is equivalent to 1 amu (atomic mass unit).

Detailed explanation-2: -Neutrons, along with protons, are subatomic particles found inside the nucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons.

Detailed explanation-3: -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-4: -(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-5: -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.
