Electron Configuration of Multielectron Atoms03:26

Electron Configuration of Multielectron Atoms

67.7K
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...

Electron Configurations

27.6K
Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest energy available), Pauli exclusion principle (no two electrons can have the same set of four quantum numbers), and Hund’s rule of maximum multiplicity (whenever possible, electrons retain unpaired spins in degenerate orbitals).
The relative energies of the subshells determine the order in which atomic orbitals are filled (1s, 2s, 2p, 3s, 3p,...

π Electron Effects on Chemical Shift: Overview

1.9K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

Valence Bond Theory

11.6K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

53.8K
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Solid State Chemistry

Background:

  • Two-dimensional (2D) antiferromagnetic (AFM) transition-metal thiophosphates (MPS3) are promising for spintronics.
  • Tuning their ground states via alloying and intercalation is known, but the role of d-shell filling is unclear.

Purpose of the Study:

  • Investigate electron doping effects in MPS3 compounds.
  • Understand how d-shell filling influences electronic and magnetic properties.
  • Explore alkali metal doping as a method to tailor 2D AFM semiconductors.

Main Methods:

  • Angle-resolved photoemission spectroscopy (ARPES)
  • X-ray photoelectron spectroscopy (XPS)
  • Density functional theory (DFT+U) calculations
  • Lithium and cesium deposition for alkali metal doping

Main Results:

  • Two doping mechanisms identified: electron donation to ligand clusters (MnPS3) or reduction of transition-metal oxidation states (FePS3, CoPS3, NiPS3).
  • Co doping in CoPS3 showed a ~1.0 eV spin-orbit splitting reduction and metallic behavior via ARPES.
  • Observed ~400 meV shift of Co-derived bands and new dispersive states above the valence band maximum.

Conclusions:

  • Established a direct correlation between d-shell filling and doping response in MPS3 materials.
  • Alkali metal doping is a viable strategy for tuning the electronic and magnetic properties of 2D AFM semiconductors.
  • Findings support the development of novel 2D materials for spintronic applications.
