2. The student uses her data to make the claim: "Methane has the
strongest intermolecular forces out of all the substances because it has
the LOWEST boiling point." Do you AGREE or DISAGREE with the claim and
why?

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

i believe the answer is true.
