Volume in angstroms3 (Atomic packing factor * Atomic mass / Density):

Radius in angstroms:

Radius expressed in units of the ground shell radius:

(Nitrogen is 3 times larger than its own ground shell)

Each shell appears to be twice the size of the previous shell so the natural thing to do is convert the radius to logarithm base 2.

Logarithm (base 2) of radius expressed in units of ground shell radius:
