Polar vs Non-polar

How can you tell if an atom is polar or non-polar?

To determine if a molecule is polar, find the electronegativities of each atom in a molecule and denote if the molecule is slightly negative or positive. From there draw the dipole moments going from the slightly positive atom to the slightly negative atom. If the dipole moments cancel out, then the molecule is nonpolar. On the other hand, if they do not cancel then the molecule is polar.

The question should be how do determine if a molecule is polar. This, just as the above answer indicates, is determined by first finding the shape of the molecule using VSEPR and then seeing if the dipole moments cancel each other out or not.
