The electronic ground state for Lithium is $1s^22s$, and not $1s^22p$. The traditional argument for why this is so is based on a screening argument that claims that the $2p$ electron is better shielded by the $1s$ electrons, and therefore higher in energy then the configuration that...
(a) Write the ground-state electron configuration for an arsenic atom, showing the number of electrons in each subshell. (b) Give one permissible set of four quantum numbers for each of the outermost electrons in a single As atom when it is in its ground state. ...

Self-consistent relativistic Dirac-Hartree-Fock calculations have been made of some lowlying electronic energies for the atoms of all elements in ground-state ds2 electron configurations. The results indicate that, contrary to some previous estimates, the ground electronic state of atomic Lr could be...
Alkali halide crystals containing impurity ions with the ns2 ground-state electronic configuration When impurity ions with the ns 2 ground-state configuration are incorporated substitutionally in alkali halide crystals, they become phosphors. Because of... PWM Jacobs - 《Journal of the Physics & Chemi...
Combined with the mixed d7 and d8L ground state of bulk LNO, this factor results in the observed peculiar electronic configuration of d8, d7 and d8L states, which appears at the interfacial NiO2 layer in 2LTO/2LNO. Next, we discuss the reconstructed band structure at the interface. ...
The B atom ground (initial) state is an open-shell system and has a 2P ground state and its principal configuration is 1s22s22p. Therefore, it requires the full power of the tensor formalism of CMCSTEP for starting from an open initial state, in which spin-symmetry is always correctly ...
The famous, yet unsolved, Fermi-Hubbard model for strongly-correlated electronic systems is a prominent target for quantum computers. However, accurately representing the Fermi-Hubbard ground state for large instances may be beyond the reach of near-term quantum hardware. Here we show experimentally ...
The ground state π -electronic angular momenta of the benzene anion and cation are calculated by the MC LCAO MO method which includes an optimum configuration interaction. Calculated values are ±1.03 ℏ for the anion and ±0.74 ℏ for the cation, while those obtained by the usual SCF wit...
We have studied the electronic structure of the carbyne CNa and the carbene Na2C using ab-initio SCF, MCSCF, and CI techniques. We find that CNa has a 4Σ- ground state with the companion 2Π state being, at best, slightly bound. The carbene Na2C has a highly bent 3A2 ground state...
