Electronic configuration, the arrangement of electrons in orbitals around an atomic nucleus. The electronic configuration of an atom in the quantum-mechanical model is stated by listing the occupied orbitals, in order of filling, with the number of elect
Up to argon, the ground-state configuration of the atoms can be obtained by filling the orbitals in the expected sequence Is, 2s, 2p, 3s, 3p. The first deviation from the hydrogenic order is apparently due to a crossover of the 3d and 4s curves. Obviously, the 3d-4s crossover has ...
Electronic configuration in outset orbitals of doping elements plays as a key factor in tuning near infrared reflection of YMn0.9M0.1O3 (M = Cr, Mn, Fe, Co, Al, Ga and In)NIR reflectionTunableIntrinsic factorsElectronic configurationNIR reflective materials have been actively explored towards ...
For example, chromium (Cr) has an atomic number of 24, which means it has 24 electrons. According to the Aufbau principle, its electronic configuration should be [Ar] 4s^2 3d^4, where [Ar] represents the configuration of argon (Ar). However, this configuration is not very stable because...

Ab initio molecular orbital calculations of the electronic structure of the sulphate ion have been performed in which three Gaussian-type functions are used to simulate each member of a minimal basis of Slater-type orbitals. Comparative... IH Hillier,VR Saunders - 《International Journal of Quantum...
structureof compressed atoms lends itself to a perturbation-theoretic analysis.It is shown, both analytically and numerically, that the increaseof the electronic energy with increasing compression depends on theelectronic configuration, as a result of the variable spatial extentof the atomic orbitals ...
Complex charge density waves in simple electronic systems of two-dimensional III2–VI3materials This study introduces a family of multiple charge-density-wave orders in 2D III2–VI3materials, including the chiral Star-of-David configuration. The charge-density-wave transitions involve both m...
Furthermore, molecular orbitals do not provide an intuitive description of electron correlation. Here we show that the 126-dimensional electronic wavefunction of benzene can be partitioned into tiles related by permutation of like-spins. Employing correlated wavefunctions, these tiles are projected onto...
