Phase 5: Construction Administration. Finally, once you have selected a contractor and construction is under way, we move into the fifth phase of the architectural design process â construction administration.
The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.
an isotope is an atom that is heavier or lighter than a normal atom of the same element. the number of protons is different. for example, carbon usually has an atomic mass of â¦ 12: 6 protons, 6 neutrons. but in carbon 14 (an isotope of carbon), there are 6 protons and 8 neutrons.toms with the SAME number of protons/electrons but DIFFERENT numbers of neutrons are called isotopes. Now ALL chemical properties of an atom are determined by the number of electrons in it ONLY (which by definition is equal to the number of protons in the nucleus).
