Three coordinate axes
1-s orbital. A small sphere appears at the origin
2-s orbital. A larger sphere appears, also centered at the origin, subsuming the 1-s orbital sphere
2-p-x orbital. A pair of teardrop-shaped spaces, together forming a 3-D figure 8, appear symmetrically about the origin along the x-axis
2-p-y orbital. A shell of the same size and shape appears symmetrically about the origin along the y-axis
2-p-z orbital. A third shell of the same size, shape, and position, oriented along the z-axis
3s orbital. A vastly larger sphere, subsuming all previous orbitals.
3-p-x orbital. A figure 8 shell similar to 2-p-x, but proportionately larger.
3-p-y and 3-p-z orbitals, following the pattern of 2-p-y and 2-p-z.
4-s orbital. Yet another large sphere containing all prior orbitals
3-d-z-squared orbital. Along the z-axis, a shape similar to 3-p-z, but larger and with a toroidal ring around the center point
3-d-x squared minus y squared orbital. Along the x-axis and the y-axis, two intersecting figure-8 shells.
3-d-x-y orbital. A shell of similar shape to the previous, but rotated 45 degrees so that the teardrop-shaped bulges in the shell are at diagonal angles between the axes rather than directly along the axes
3-d-x-z and 3-d-y-z. The shells equivalent to the prior shell, but along the other two pairs of two axes, respectively
Overview of all shells, highlighting one at a time. By now, the complex overlapping three-dimensional configuration is recognizably a large atom.
