"WebElectronegativity can tell us a lot about how different elements will bond to each other and which type of bond it will be. If the electronegativity difference between the two elements involved in bonding is less than 0.4 then the bond will be nonpolar covalent. If the difference is between 0.4 and 1.7 then the bond is considered polar covalent. " - In electronegativity value
