Accepted Answer

The nucleus of an atom consists of protons and neutrons, which are collectively called nucleons. Electrons are located outside the nucleus in the electron cloud. Protons have a positive charge, while neutrons have no charge. The number of protons in the nucleus determines the atomic number and identity of the element, while the total number of protons and neutrons determines the atomic mass.
