Question

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

Explanation:

In a water molecule ($H_2O$), hydrogen atoms share electrons with the oxygen atom through covalent bonds. The oxygen atom is more electronegative, giving it a slight negative charge. Water is a universal solvent and can dissolve many substances. Also, water molecules in the liquid - state move randomly around each other due to thermal energy.

Answer:

Water molecules move randomly around each other.
