Height to architectural top. Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building. This includes spires, but does not include antennae, signage, flagpoles or other functional-technical equipment.
Nucleons are composite particles made up of protons and neutrons. The protons and neutrons collectively present in the nucleus of an atom are called nucleons. The nucleons occupy very small space inside the nucleus. Nucleons are an important part of an atomic nucleus and therefore, they are important in particle physics.
Nucleons are either protons or neutrons and the total number of nucleons is given the symbol A (also known as the mass number). The total number of protons within the nucleus is called the atomic number and given the symbol Z.Protons and neutrons have a mass of 1, protons are positively charged and neutrons have no charge. 1  A (mass number): total number of nucleons = protons + neutrons.2  Z (atomic number): number of protons. great many different configurations of the nucleus may occur. In each case, the atomic number defines the element, i.e. it is the number of protons that determines that carbon (having 6 protons) is carbon.
