Lado's Periodic Table Series Analysis
By Solomon F Lado, a mathematical analysis.
Abstract (full paper):
"There is a periodic table, at least in terms of atomic number and electronic configuration, for every positive integer, c >= 2, with a capacity of 20c2 – 21c + 1 elements, where c is the construction index, and c equals one plus the maximum number of electrons per orbital of an atom. The c-construction index and the c-construction-index formulae are unique to this report. The maximum number of potential orbitals per sub-shell of an atom = 3n-1 where n is the index of the s, p, d, and f sub-shells":
