Question

which side of the water molecule has a positive charge? hydrogen oxygen

Explanation:

Water is a polar molecule. The oxygen atom has a higher electronegativity than hydrogen atoms. Electronegativity is the ability of an atom to attract electrons in a chemical bond. In a water molecule ($H_2O$), the oxygen atom attracts the shared electrons more strongly than the hydrogen atoms. As a result, the oxygen side of the water molecule has a partial negative charge ($\delta -$), and the hydrogen side has a partial positive charge ($\delta +$).

Answer:

hydrogen
