Determining shapes of molecules
WebJul 3, 2024 · Getty Images/JC559. Valence Shell Electron Pair Repulsion Theory ( VSEPR) is a molecular model to predict the geometry of the atoms making up a molecule where the electrostatic forces between a molecule's valence electrons are minimized around a central atom . The theory is also known as Gillespie–Nyholm theory, after the … WebSome common shapes of simple molecules include: Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear …

WebThe valence shell electron-pair repulsion (VSEPR) model is used to predict the shapes of molecules and polyatomic ions. VSEPR is based on the idea that the “groups” or “clouds” of electrons surrounding an atom will adopt an arrangement that minimizes the repulsions between them. In this video, we look at examples of molecules in which ... WebJul 28, 2024 · The number of bonds coming from the central atom and the number of lone pairs will determine the shape of the molecule.
