Which chemical condition describes the electrons in a water molecule being shared unequally between the hydrogen and oxygen atoms?

When electrons shared unequal atoms such as hydrogen and oxygen atom, one atom will get more of the common electrons and it will be slightly negatively charged. The other atoms who gets less electron will be slightly positively charged. This chemical condition describes water as a polar molecule. The oxygen atom pulls the shared electrons more strongly than do the hydrogen atoms within each of the two polar covalent bonds.

i do not get it   at all
