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.
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons (none in hydrogen-1). Protons and neutrons are called nucleons. Over 99.94% of the atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, that atom is electrically neutral.
