Why does the Periodic Table Look Gaussian when organized like this?

Question

When the periodic table elements are organized in terms of their orbitals (s,p,d,f; on an imaginary X axis); energy levels (1 through 8; on an imaginary Y axis); and electron filling rules (1s2, 2s2, etc), is it a coincidence that the resulting pattern looks like a Gaussian distribution?)

Answer 1

bell-shaped curve? it is a general statistical law that a sum of many different random variables will look Gaussian ...
