Detailed explanation-1: -Like protons, neutrons are bound into the atom’s nucleus as a result of the strong nuclear force. Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2, 000 times as massive as an electron).
Detailed explanation-2: -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-3: -Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
Detailed explanation-4: -proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1, 836 times the mass of an electron.
