The 2024 paper Chemical Bonding and the Role of Node-Induced Electron Confinement appears to argue that, as atoms approach one another, chemical bonding is governed by an increase in the kinetic energy of the electrons caused by one or maybe more of the following mechanisms:

• Pauli repulsion from core electrons, or more generally, electron confinement induced by the presence of nodes,
• orbital contraction,
• polarization.

Is it reasonable to say that most chemists would consider these three mechanisms sufficient to explain the formation of chemical bonds?
