The electronegitivity of the elements in the bond.
Electronegativity
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Polarity is related to bond strength because the bigger the difference in electronegativity, the higher the bond energy will be. This will then give rise to a much stronger bond.
bond polarity is the polarity particular bond within a molecule, while molecular polarity is the polarity of the whole molecule. take for example water (H20): you could find the bond polarity of each H-0 bond (polar covalent), or the polarity of the whole molecule together (polar, because the electronegativity of oxygen is higher than the hydrogen atoms)
PH5 does not exist. If it did, the bonds would possible be polar as there is an electrnegativivty difference between P and H. PH3 does exist and will have bond polarity.
nonpolar
dipole moments increase with the polarity

The bond dipole moment measure the polarity of a chemical bond.
What determines a molecule's solubility degree in water is its polarity. Equals dissolve.
Polarity
The more electronegative atom will make its end of the bond more negative.-Apex
