Learning Goal:
To use electronegativity or metal versus nonmetal
classifications to distinguish covalent, polar
covalent, and ionic bonds.
When two bonded atoms attract electrons with
equal strength, the result is a nonpolar covalent
bond. A polar covalent bond is one in which the
electrons are unequally shared between the atoms.
An ionic bond results when the sharing is so
unequal that fully charged ions form.
Electronegativity difference can be used to predict
bond type. One method to classify bonds based on
this difference can be described as follows. If the
electronegativities differ by less than 0.4 units, the
bond can be classified as nonpolar covalent. If the
difference is between 0.4 and 2.0 units, the bond is
classified as polar covalent, and if the difference is
more than 2.0 units, the bond is substantially ionic.
If you are not given electronegativity values, you
can still predict the bond type using the
periodic table. Metals have low electronegativity
compared to nonmetals. So in general, we can
predict that any metal-nonmetal combination will
be ionic and any nonmetal-nonmetal combination
will be covalent. If electronegativity values aren't
given, you should assume that a covalent bond is
polar unless it is between two atoms of the same
element.
