Oxidation-state assignment: EN-based bond partition; Σ OS = molecular charge

Layer 2 — Chemistryin the chemical-nomenclature subtree

Oxidation-state assignment rules (IUPAC recommendations 2016, Karen et al.). For each atom A in the Lewis structure: (i) list its valence electrons v_A in its free atomic state; (ii) partition each bond's two electrons entirely to the…
