Question

which statement is true about water molecules?
water molecules move randomly around each other
water molecules cannot dissolve many substances
the hydrogen atoms do not share electrons.
the oxygen atom has a slight negative charge

Explanation:

Water is a polar molecule. Oxygen is more electronegative than hydrogen, so it attracts the shared - electrons more strongly, giving the oxygen atom a slight negative charge. Water molecules are in constant random motion in the liquid state. Water is a universal solvent and can dissolve many substances. In a water molecule, hydrogen and oxygen share electrons in a covalent bond.

Answer:

The oxygen atom has a slight negative charge
