H2O has the strongest polar covalent bond as it has the greatest difference in electronegativities between the atoms. H2 - not polar, same atom no electronegativity difference O2 - not polar, same atom no electronegativity difference CO2 - ...

Yes.If its very polar then there exists permanent dipole-dipole moments which are stronger than induced dipole moments BUT not as strong an ionic bond.

when one atom is more likely to attract the electron pair strongly than the other, the bond is said to be polarized.

They're about the same. There is a huge overlap in the ranges of strengths of ionic and covalent bonds, so determining which one is "stronger" in general is a dodgy exercise. The trouble with the comparison is that different che...

The electrons between the two elements aren't shared equally and slightly polarizes both sides, or gives it a positive or negative charge.

A polar covalent bond is created when one atom in a bond is more electronegative than the other. What this means is that the electrons from that bond have a greater draw to the more electronegative atom than the other. Since electrons tend ...

A polar covalent bond is formed when 2 atoms are sharing the same electron unequally. It occurs because one of the atoms has a stronger affinity for electrons that the other.
