In H2O the electrons are shared by the oxygen atom and two hydrogen atoms. Although there are two hydrogen atoms, the electro-negativity (or ability to attract electrons) of the oxygen is greater than the hydrogens, therefore the electrons are pulled greater towards the oxygen resulting in the oxygen becoming "negatively charged" this results in the molecule becoming what is known as a "dipolar molecule". This is what causes water to be attracted to each other as each molecule has a positive and negative pole.

Valence electrons
In a covalent bond, electrons are shared between atoms to form a stable molecule. These shared electrons move between the nuclei of the bonded atoms, creating a strong bond that holds the atoms together. The shared electrons are attracted to both nuclei, thus keeping the atoms in close proximity to each other.
A covalent bond in which electrons are shared unequally is called a polar covalent bond. This type of bond occurs when one atom has a greater pull on the shared electrons, creating partial charges on the atoms involved in the bond.
No. A polar bond is formed when electrons are shared unevenly. A nonpolar bond indicates even sharing of electrons.
A covalent bond! When the electrons are shared unequally due to a difference in electronegativity between the atoms being bonded it is called a polar covalent bond
electrons are shared unequally between atoms.

polar bonds
A polar covalent bond involves a particle in which electrons are shared unequally. This occurs when the difference in electronegativity between the atoms is significant enough to cause a partial negative charge on one atom and a partial positive charge on the other.
