This article is a stub. It needs to be expanded.

The classification is intentionally kept nonstandard here.

(wiki-TODO: Add visual mermaid diagram.)

Nuclear shielding effects

  • Bonding orbitals – shielding nuclei by wave-function anti-node in-between
  • Anti-bonding orbitals – exposing nuclei by wave-function node in-between

Delocalization stabilization (dual to Pauli repulsion!)

More delocalization and fewer nodes act energy lowering and thus bond-stabilizing

  • Multicenter electron deficient bonds (e.g. diborane)
  • Conjugated systems (e.g. graphitic/aromatic systems)
  • Metallic stabilization (e.g. pyrite, titanium nonmetallides)

Polar/ioninc stabilization

  • stabilization due to electron polarity shifts due to electronegativity differences
    (e.g. periclase MgO, bromellite BeO)
