Application of the Q-DFT Pauli Correlated Approximation to Atoms and Negative Ions, and Correlation-Kinetic effects are once again ignored. The fact that Coulomb correlations are not considered is of course evident as the choice of the approximate wave function is a Slater determinant. Note, however, that the contributions of Correlation-Kinetic effects to (1) the kinetic energy,
