* Molecular Geometry: KrF₂ has a linear molecular geometry. This means the two fluorine atoms are positioned on opposite sides of the krypton atom.
* Electronegativity Difference: Fluorine is much more electronegative than krypton. This means the fluorine atoms pull the shared electrons in the Kr-F bonds closer to themselves, creating partial negative charges (δ-) on the fluorine atoms and a partial positive charge (δ+) on the krypton atom.
* Dipole Moment: Due to the uneven distribution of electron density, a permanent dipole moment is created. This dipole moment arises from the vector sum of the individual bond dipoles.
Therefore, even though KrF₂ has a linear geometry, the significant electronegativity difference between Kr and F atoms results in a polar molecule.
