Which type of bonds hold atoms together in water molecule

Polar covalent bonds hold atoms together in a water (H2O) molecule since H (non-metal) is bonded to O (which is also a non-metal), so they'll need to SHARE electrons (covalent), not to mention H2O is POLAR because of O (-> O has a [-] charge compared to H [+]),  so there's an unequal sharing of electrons.

This is the most closely resembles the model.
