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.
Atoms are part of elements. In other words, each element is made up of atoms. Atoms are made up protons, electrons and neutrons, also called subatomic particles. Together, protons, neutrons and electrons, are called nucleons. Protons, neutrons and electrons are made up of even smaller particles, called quarks. The center of an atom is called a nucleus. The nucleus is pushed together by the strong nuclear force. The nucleus is made up of protons and neutrons. Protons are positively charged and neutrons have no charge. Around the nucleus are electrons.
