Relationship between the pauli principle and the thermodynamical/chemical stability

  • #1
hi,

i believe there is a clear cut relationship between the pauli exclusion principle and the thermodynamical/chemical stability in chemistry. the pauli principle rises the energy level, and stability occurs for the lowest energy states. does that mean that a consequence of the pauli principle is necessarily less stability, and that fermions structures or substructures(electron shells) are necessarily less stable, more reactive than bosons?

thank you for your reply

I'll try to answer the first part of your post. The pairing of electrons with opposite spin in an orbital has an energy cost associated with it This explains why we see half-filled shells before the system pairs electrons in an orbital (and explains the discontinuities in the ionization energies across a row of the periodic table).
