Pauli Shell Structure Context

ID: physics.atomic.pauli_shell_structure

Pauli exclusion bars identical fermions from the same complete quantum state, not from every overlapping spatial region. Two electrons can share a spatial orbital when their spin states differ; a fermion and a boson are different particle types, so Pauli exclusion does not bar their spatial overlap. Mass alone does not decide these statistics.

Status: canonical_reference

Uncertainty

• Whether particles overlap in a particular system depends on their states and interactions; this concept alone does not determine a measured position or material behavior.

Claim boundaries

• A shared spatial region is not the same as a shared complete quantum state.
• Do not infer that all matter is fermionic, all bosons are massless, or particles behave as rigid classical volumes.
• This badge does not establish the position or interaction of particles in a particular system.
