Meaning of electrostatic attraction and repulsion. There is a minimum energy state that an electron can … Electron pair repulsion is used to predict the geometry of a molecule or a polyatomic ion. Die repulsiven Kräfte kommen durch Pauli-Repulsion zustande, sind also dadurch bedingt, dass sich Elektronen mit gleichem Spin abstoßen (falls alle anderen Quantenzahlen gleich sind), wenn die Orbitale übereinander geschoben werden. Das Modell wurde von Ronald Gillespie und Ronald Nyholm entwickelt und wird deshalb auch Gillespie-Nyholm-Theorie genannt..

The Valence Shell Electron Pair Repulsion (VSEPR) Theory can be used to predict the shapes of molecules based on the number of electron pairs around the central atom.. The best accepted definition of electron orbits/energy levels is given by the Schroedinger wave equation. VSEPR approach to find molecular structure - definition VSEPR theory is used to find out the geometry of a molecule.According to the VSEPR theory, the electrons repel one another and will, therefore, adopt an arrangement that minimises this repulsion.
