The internal field is a sum of fields representative respectively of electron correlations due to the Pauli principle and Coulomb repulsion; the electron density; kinetic effects; and an internal magnetic field. The energy can be expressed in integral virial form in terms of these fields. The ...

These two effects are the orthogonality of the molecular orbitals (MOs) and the electron-exchange interactions between the LMOs. This result is in direct contradiction to the presently accepted valence shell electron pair repulsion (VSEPR) model, which attributes the geometries of molecules to Pauli ...
The Pauli exclusion principle played a decisive role in understanding the regularities underlying the filling of the electron shells of the atom. It served as the starting point for an explanation of atomic and molecular spectra. In the quantum theory of the solid state, the application of the ...

When two electrons are on neighbouring atoms, one spin-paired state localises electron density between the two nuclei. The electrostatic attraction to both nuclei more than compensates for the increased repulsion between electrons, and a chemical bond is formed. Within a single atom, an atomic ...
So my question is why can't 2 object be at the exact same potion, (i.e. overlap). Why can't a +ve quark and electron just merge. In an universe where there is no force caused due to charge, why can't we just walk through a solid wall. ...
by the number and arrangement of electrons. The configuration of these electrons follows the principles of quantum mechanics and thePauli exclusion principle. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor determining it...
electron-electron repulsion energies since these are the essence of the energy difference between the singlet and triplet states. Two closed-shell zwitterionic singlet states are also possible (ψ S+,CS and ψ S-,CS ), and are given below. In ...
An example is the neutral helium atom, which has two bound electrons, both of which can occupy the lowest-energy (1s) states by acquiring opposite spin; as spin is part of the quantum state of the electron, the two electrons are in different quantum states and do not violate the Pauli ...
