Higher the electronegativity of an atom, higher is its tendency to pull the shared electron cloud towards itself. To further discuss the molecular geometry of molecules, the geometrical shape of the molecule may be characterized as asymmetric or distorted. As a result, the F-atoms strongly attract the shared electron cloud from each I-F bond in the IF 3 molecule. If the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. It also aids with understanding the bonds formed in the molecule and the electrons not participating in any bond formation.
