What determines polar and non-polar covalent bonds?

The difference in electronegativity of the atoms involved in the bond determines polarity. Difference in electronegativity means the electrons like to hang out closer to one atom than to the other, and this is called polar. When there is no difference in electronegativity (bond between atoms of the same element), electrons are shared evenly and this is called nonpolar.

to add on the comment above, is when to determining a ionic, polar or non polar covalent bond, you find the difference In electronegativity and if the difference range from 0 to 0.4 then it is a covalent bond and if it ranges from .5 to 1.7 then it is a polar covalent bond, if it is more than 1.7 then it is an ionic bond.

Do they provide us with electronegative values to figure out whether it is polar covalent, non-polar covalent, or ionic?

Can someone give an example of a polar covalent bond?

Hi Endri,
here is one:
C-Cl, Carbon has an electronegativity of 2.5 and Chlorine has an electronegativity of 3= 0.5 which is a polar covalent bond between the two.

They generally won't. You usually just use the electronegativity trends of the periodic table to determine the type of bonds. At least that's what most practice problems I've done have been like.

Polarity depends on the electronegativity difference. Ranges 0 - 0.4 is non-polar, 0.5 - 1.7 is polar, 1.7 < is ionic.
