Baryons can never be considered present in every atom as some atoms always skip the experimental assurance of their presence.

Since quarks are [[fermion]]s, the [[spin-statistics theorem]] implies that the [[wavefunction]] of a baryon must be antisymmetric under exchange of any two quarks. This antisymmetric wavefunction is obtained by making it fully antisymmetric in color, discussed below, and symmetric in flavor, spin and space put together. With three flavors, the decomposition in flavor is
