Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. The number of protons defines an element (hydrogen has one proton, helium has two, and so on) of the atom. They display their learning in the form of Bohr models depicting the excited state of the atoms. Adjust the dowel along the diameter of the circle so one end just touches its inner edge. Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass. The simplest atom to consider is the helium atom in its singlet state for which the 1s orbital is occupied by two electrons of opposite spin. There are numerous collections from which to build three to five molecules from given kits of atoms. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. In the most common variety of helium, the nucleus also contains two neutrons, which have nearly the same mass as the proton but carry no charge. Drill a 1/4-inch hole though the spheres of the nucleus so the dowel passes through the diagonal of the square pattern. Since an alpha particle is the same as the nucleus of a helium atom it needs to capture two electrons to reach a stable state – presumably as a helium atom. This is the model designed by Dr. Niels Bohr, a physicist who won the 1922 Nobel Prize in physics for his discoveries in atomic structure and radiation. Seeing is believing! Thread the nucleus onto the dowel and lay it on a flat surface. The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure \(\PageIndex{1}\)). (a) An aspiring physicist wants to build a scale model of a hydrogen atom for her science fair project. It depends on what kind of atom you want to make… so I will do a Helium atom. Two neutrons. The reason is that at the atomic scale you have to take into account the quantum mechanical aspects of the individual particles, which behave not as billiard balls but as spread out wave functions. Since an alpha particle is the same as the nucleus of a helium atom it needs to capture two electrons to reach a stable state – presumably as a helium atom. Two electrons orbit the nucleus. Optionally, use a marker or something to draw a “+” on the protons and a “N” on the neutrons. The attraction of electrons to protons was a magic moment in the history of the Universe. The next most abundant form has one less N, and the artificially created forms, with different numbers of Ns, all disintegrate radioactively within less than one second. Before you begin, look through the Periodic Table of Elements and pick an atom.
