This paper examines the topology and stability of ground state isotopes of major elements. According to Unified Field Theory (UFT), a proton has the shape of an octahedron. The nuclei result from protons and neutrons piling up. Since the strong forces are along the axes of the octahedron of protons and neutron, the structure of ground state isotopes of any given element can be logically induced. Only two of three axes of the octahedron nucleus have strong interactive forces internally. The structure starts with one or two base squares and accumulates smaller squares along the axis of the base squares in both directions. The possible proton base structures are square shaped. For example, the Technetium nucleus has one proton too many to be symmetrical. Therefore, no stable isotopes of Technetium can be found. %K Nuclear Physics %K Particle Physics %K Unified Field Theory %U http://pubs.sciepub.com/ijp/2/1/4/index.html
