Protons and neutrons are also called

Protons and neutrons are the two types of particles found in the atomic nucleus. The term 'nucleon' is used to refer collectively to either a proton or a neutron, making nucleons the correct answer. Isotopes refer to atoms of the same element with different numbers of neutrons, isobars are atoms with the same mass number but different atomic numbers, and elements are pure substances consisting of only one type of atom.
