Water (H2O) is an example.

Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.
Check the electronegativities of the atoms in the bond. The bond will be polar if there is a difference in electronegativity. The most electronegative element will attract the bonding eletrons to it becoming slightly negatively charged. The other end of the bond will become slightly positively charged. For example a bond between carbon and chlorine, C-Cl: C electronegativity 2.55 Cl electronegativity 3.16 The bond will be polar because of the difference in electronegativity, and Cl will be slightly negative, carbon slightly positive.
A bond between two atoms of the same element are non-polar.
A bond between two atoms of the same element are non-polar.
A bond between two atoms of the same element are non-polar.
a very polar bond.
An example of a non-polar covalent bond is the bond between two chlorine atoms in a chlorine molecule (Cl2). In this bond, the electrons are shared equally between the two chlorine atoms, resulting in no separation of charge and making it a non-polar covalent bond.
HCl has the polar bond. Another polar bond is H2O, or water. And all those bonds are polar in which two atoms have a difference of electronegativities between 0.5 and 1.7 and their dipole moment is not zero.

In a non-polar covalent bond the sharing of electrons between the atoms is equal.This depends on the difference between the electronegativities involved in the bond; when a difference don't exist or is minimal the bond is non-polar.As an example the diatomic hydrogen bond is non-polar.

For a bond to be non-polar covalent, the two atoms involved in the bond would have to have the same electronegativity, so the ∆EN (difference in electronegativity) is zero. An example would be F2 or Cl2 where two halogen atoms bond together, and the ∆EN is zero.
