Covalent Bond Ionic Bond
F₂ shares the electrons equally but sometimes one of the
atoms (the more electronegative one) will exert a stronger pull
on the electrons in the bond-not enough to make the bond
ionic, however, enough to keep the electrons on one side of the
molecule more than the other Polar bond
The valence electrons can indicate by dots or lines.
EXCEPTION OF THE OCTET RULE: on the handout.
Lone pair: alone on 1 atom.
Bonded pair: shared by 2 atoms.
3. Geometry of molecules and ions, structural isonerism of simple organic molecules and coordination complexes, dipole moments of molecules, relations of properties to structure.
27. A molecule with the formula XY₂ whose atoms are arranged linearly could have a central atom with which of the following hybridizations.
