Atomic Radius/radius of ground shell. From Template:Periodic table (Allotropes).

Green parabola at bottom:
 * 1 at zero (far left)
 * 0 at 19 (Manganese, D 5/2)
 * 0.5 at 32.435 (far right)

Yellow parabola is 4 times the height of the green parabola.

Orange parabola is 8 times the height of the green parabola.

All parabolas with the same color are identical and all parabolas have their minimum value at 19.

Vertically the parabolas have minimum value at 0, 1, 2, 3, 4, and 4.75

D orbital electrons seem to correspond to the orange and yellow parabolas of one level.

P orbital electrons seem to correspond to the yellow parabola of one level and the orange parabola one level below.

S orbital electrons seem to correspond to the yellow parabola of one level and the orange parabola two levels below.
