It depends on the electronegativity of the atoms in the molecule. When an atom has a higher electronegativity than the others in the molecule, the electrons will have a higher affinity for that side, making the molecule polar.
Take a look at their electronegativity values for this one. Electronegativity is the relative attraction that a atom in a molecule has for the shared pair of electrons in a covalent bond. Salt is Sodium Chloride which is NaCl. Na has an electronegativity value of 0.93. Cl has an electronegativity value of 3.16. The difference between the two is 2.23. This is much higher than 1.7 (a pure covalent bond e.g. Oxygen-Oxygen bond O2) therefore it is a highly ionic compound. If this was less than 1.7 it would be a polar covalent molecule.
A covalent bond is only polar if there is a difference in electronegativity between the two atoms. Since the two oxygen atoms in an O2 molecule are identical there is no such difference.
A covalent bond, as in all diatomic elements. To be specific, a nonpolar covalent bond, since the electronegativity values are identical
As I originally stated in my original answer, the bonds in a molecule of OF2 are covalent. The electronegativity difference between them, according to the Pauling values is 0.54, which indicates a slightly polar covalent bond, in which Fluorine has the higher electronegativity value.

Nonpolar covalent bond; the electronegativity values are identical.
This is a nonpolar molecule.

molecule of iodine is made up of similar kind of iodine atoms .So there is no difference in the electronegativity. Hence,it forms non-polar covalent bond.

Yes, but not always equally. Depends on the elements electronegativity variance. H2O is a polar covalent bond because the oxygen has much stronger electronegativity than the hydrogens, so their are slight charges on the ends of the molecule. NO, nitrous oxide, is just covalent because the elements are of pretty much equal electronegativity.

he bonds within the molecule are all covalent. The C-O and O-H bond are polar covalent because of the high electronegativity of O.
Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.
