Detailed explanation-1: -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.
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: -Hydrogen (Protium-1H1) is the only element that does not contain any neutrons in its nucleus. Q. Name an atom which does not contain all three subatomic particles-proton, electron and neutron.
Detailed explanation-4: -Neutron is electrically neutral and proton is positively charged and an electron is negatively charged. In an atom, the number of protons is equal to the number of electrons. Hence, the overall charge in an atom is zero and it is a neutral particle.
