Vertical axis = n + l

Color indicates crystal structure

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

Radius/Radius of ground shell:

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

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

Log2(radius/radius of ground shell):

Notice how small hydrogen and helium are!
