The term spin pairing is used freely with respect to particle interactions, but it is misleading because it is not the spins per se that pair. Electron Pair Repulsion Definition . For example, the force between two parallel wires carrying currents in the same direction is attractive. The principle that electron pairs around a central atom tend to orient themselves as far apart as possible. ( Log Out /  Learn more.

Well, it’s possible a molecule with a closed cycle may have an atom that appears to be sp3 hybridized, so that you might mistakenly conclude the atom has a lone pair, and you might even conclude that the molecule is not aromatic. Helmenstine, Anne Marie, Ph.D. "Electron Pair Repulsion Definition." The name SPIN Selling comes from a highly influential book with that same title by Neil Rackham, originally published in 2000.

Definition and synonyms of spin from the online English dictionary from Macmillan Education.. She has taught science courses at the high school, college, and graduate levels. The Pauli exclusion principle declares that there can only be a maximum of two electrons for every one orientation, and the two electrons must be opposite in spin direction; meaning one electron has \(m_s = +\frac{1}{2}\) and the other electron has \(m_s = -\frac{1}{2}\). Helmenstine, Anne Marie, Ph.D. (2020, August 27). 61, NO. Valence Shell Electron Pair Repulsion (VSEPR) theory constitutes one of the pillars of theoretical predictive chemistry. .6 2 <
