In recent years, scientists Enthusiastically interested in the study of hyper-atoms, a paper published in Science in the United States revealed that a super-atomic structure of Al was found. This super-atom (Al_ (13)) has 1 aluminum atom in the center and 12 aluminum atoms in The surface forms a trigonal icosahedron structure, which is the most stable when it has 40 valence electrons
