This set contains enough parts to make 14 easy-to-assemble atomic orbitals. The pink and purple, pear-shaped lobes represent the 2-wave phase. Opaque white spheres represent atomic nuclei. Each model comes with its own clear, colorless base for display purposes. Approximate model heights, including the base, are 5 cm (s orbital), 9 cm (p orbital), and 8 cm (d orbital).
