Bonding and geometry
WebOct 12, 2024 · A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction. Web-Electron geometry is the arrangement of the electron groups.-Molecular geometry is the geometrical arrangements of the atoms. -When a molecule contains one or more lone pairs, then the molecular geometry differs from the electron geometry. This is because the lone pair exerts slightly greater repulsion than a bonding pair.
