   4# Periodic Table Shells from Phi-Ladder — Tier F Chemistry
   5
   6The electron shell capacities in the periodic table are:
   72, 8, 18, 32 = 2n² for n = 1, 2, 3, 4.
   8
   9These are NOT phi-ladder, but the NUMBER of periodic table blocks:
  10s-block (2), p-block (6), d-block (10), f-block (14) total = 32 = 2^5.
  11
  12The five canonical block types (s, p, d, f, g-predicted) = configDim D = 5.
  13
  14For the phi-ladder connection: the principal quantum number n steps
  15give periods of lengths on the phi-ladder pattern:
  16- Period 1: 2 elements (1s²)
  17- Period 2: 8 elements  
  18- Period 3: 8 elements
  19- Period 4: 18 elements
  20- Period 5: 18 elements
  21- Period 6: 32 elements
  22- Period 7: 32 elements
