Detailed explanation-1: -Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than . 01% of the volume of the atom, but typically contains more than 99.9% of the mass of the atom.

Detailed explanation-2: -Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.

Detailed explanation-3: -Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. 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.
