Atom size vs. boiling point
How does the atomic radius of an atom correlate to its boiling point/melting point?

Re: Atom size vs. boiling point
A bigger atomic radii increases the polarizability of the molecule which increases the amount of induced dipole- induced dipole forces in a body of that molecule. More intermolecular forces will lead to a higher boiling point. In short, bigger atomic size leads to a higher boiling point.

Re: Atom size vs. boiling point
To add on, a bigger atomic radii would mean they have more electrons and more opportunities to create dipole-dipole forces. The larger the atomic radii basically means larger atomic size, which would therefore create more London-dispersion forces. Since bigger atomic size means stronger intermolecular forces, the boiling point must be higher as well.

Re: Atom size vs. boiling point
Larger molecules and atoms are also more massive, and therefore, it takes more energy to make that substance change states.

Re: Atom size vs. boiling point
The strength of the Van Der Waal's forces in the atom increases because of the greater number of electrons, which would increase the polarizability and thus the strength of IMFs.
