# Which of the following elements experiences the greatest london dispersion forces: fluorine, chlorine, bromine, or iodine?

At room temperature ${F}_{2}$ and $C {l}_{2}$ are gases, $B {r}_{2}$ is a liquid (and one of the few elemental liquids on the Periodic Table), and ${I}_{2}$ is a solid. While the $I - I$ bond, the intramolecular bond, is weakest, the intermolecular bonds are sufficiently strong to stabilize the solid.
