The shapes of molecules The Mole RSC Education
WebbElectron pairs arrange themselves so they are as far apart as possible (electron pair repulsion theory). In a covalent compound, the number of electron pairs around the central atom determines the shape of the molecule. An electron pair shared between two atoms is called a bonding pair (BP) Webb10 aug. 2024 · 4.12: Shapes and Properties- Polar and Nonpolar Molecules Last updated Aug 10, 2024 4.11: Molecular Shapes- The VSEPR Theory 5: Chemical Accounting Learning Objective Determine if a molecule is polar or nonpolar.
