Iodine is the fifth element with electrons in the 5p orbital. It has the same electron configuration as bromine, just one shell larger. Like chlorine and bromine, iodine can support multiple possible molecular geometries, and can sustain multiply bonded atoms (with stronger electronegativity than iodine). (The wireframe simply indicates the boundary of the n=5 shell, since there are no electrons defining the boundary of its sphere.)
