 how much attraction an element has to electrons
 when bonded things different in electronegativity is too high, one basically steals the electron from the other forming an ionic bond, and if it's in the middle then it's polar, and if the difference isnt large than the 2 play nice and share it with a covalent

 when 2 bonding atoms have an $\Delta$ EN greater than 0.5 and less than 1.7, it's a polar covalent bond 

-polar covalents have an imbalance of electrons
+polar covalents have an imbalance of electrons, causing partial positive charges and partial negative charges, the atom with the stronger EN pulls the electron more but not enough to completely take it, making the electron closer and giving it a partial negative charge
