The smaller dipole moment in CO , the reason to be predicted. Concept Introduction : Lewis structure: The bonding between atoms in a molecule satisfies the octet rule of valence electrons and the lone pairs also exist in the molecule. The electron is represented as dots. Formal charge: The charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless its relative electronegativity. Ionic bond: The electrostatic force of attraction between two oppositely charged ions result in ionic bonding. Covalent bond: The equal sharing of two electrons between two atoms (identical atoms or nearly close electronegativity values) in a compound.
