Spin pair repulsion
WebAbstract Valence-shell electron-pair repulsion (VSEPR) theory constitutes one of the pillars of theoretical predictive chemistry. It was proposed even before the advent of the concept of “spin”, and it is still a very useful tool in chemistry. WebFor fermions, this interaction is sometimes called Pauli repulsion and is related to the Pauli exclusion principle. For bosons, the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as …

WebJan 1, 2011 · Spin-pair repulsion Electrons in the same atomic orbital in a subshell repel each other more than electrons in different atomic orbitals which makes it easier to remove an electron (which is why the first ionization energy is always the lowest) So, the first ionisation energy increases across a period and decreases down a group WebSpin-pair repulsion We need to know how each of these factors affect the ionisation energies. Spin Pairing Energy - Chemistry LibreTexts. Here the first drop is due to a slight increase in distance from nucleus as outer electron occupies a new subshell p subshell slightly further away from the nucleus. The second drop is due to spin pair ...
