Question

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

Explanation:

In a water molecule, oxygen is more electronegative than hydrogen. This causes oxygen to attract the shared - electrons more strongly, resulting in a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms. Water molecules in the liquid state move randomly around each other. Water is a universal solvent and can dissolve many substances. In a water molecule, hydrogen atoms share electrons with the oxygen atom through covalent bonds.

Answer:

The oxygen atom has a slight negative charge.
