Molecular models of two different substances are shown below. In the molecule on the left, the oxygen atom pulls on electrons more strongly than
the hydrogen atoms. In the molecule on the right, the two oxygen atoms pull
on the shared electrons with the same strength.
Water molecule, H2O Oxygen molecule, O2

each other. Why does this happen?
A. They are both polar.
B. One is polar and one is nonpolar.
C. They contain different elements.
