How do you know if a compound is polar or nonpolar??
ie: TeF4

What makes a molecule polar is if there is a dipole moment. This means that you can see one end with a positive charge and an opposite end with a negative charge. Water is polar because it takes a bent form where oxygen, a negative atom, is on one end and the hydrogens, positive atoms, are on the other end. Carbon dioxide, on the other hand, is nonpolar because both ends are negative, so a dipole moment doesn't form.
When looking at a molecule, you need to know the shape and what charge an atom will normally take (positive or negative).

Its non-polar, click on this site to see its structure. You can verify that it is non-polar

You take their electronegativites. (there's a chart somewhere in the book). Subtract the two negativities. If it is 0-0.29, it is nonpolar. If it is 0.3-1.69, it is polar. If it is 1.7-3.3, it is ionic.

if its polar it has a positive and negative parts of the magnetic field
