Step 1: Build the modified periodic table

In this hypothetical system, for principal quantum number ,  ranges from  to  (instead of  to ).

:  → subshells: 1s (2e), 1p (6e), 1d (10e) → total = 18 electrons

:  → subshells: 2s (2e), 2p (6e), 2d (10e), 2f (14e) → total = 32 electrons

Step 2: Fill electrons in order (using Aufbau)

Following  rule:
- 1s: Z = 1–2
- 1p: Z = 3–8
- 1d: Z = 9–18 (but 2s has , same as 1p's last; let's use strict Aufbau)

Actually using  values:
- 1s (): 2e → Z=1,2
- 1p
