Which contributes to the polarity of a water molecule?

Oxygen and two hydrogen molecules

Explanation:

Polarity simply implies a molecules with positive and negatively charged ends.

The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds.

While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction.
