There will be an explosion so try to stay away when you mix!

The halogens react with metals to make salts called metal halides.

metal + halogen → metal halide

A halogen can displace a another halogen, lower in the group, from a solution if its salt. We look at reactions where chlorine displaces iodine and bromine; then at bromine displacing iodine. 2NaX + Y2 = 2NaY + X2

Van der Waal dispersion forces are the intermolecular forces (WEAK) that mediate attraction between halogens. As the electron radii increases it becomes more pliable (think of a nerf ball). This softness in the electron cloud causes the electron density to shift slightly from one side to the other. As electron density increases so does the negative charge. With the corresponding side experiencing a decrease in electron density causing it to become slightly positive (less negative). This is called a Dipole Moment. When you have dipole moments between two atoms there's a weak level of attraction between the opposite poles (-/+) * (-/+). This stuff can get confusing but an easy mechanism to compare it to would be hydrogen bridge bonding between water molecules. The electron dense oxygen side is more negative as it pulls on the electrons from the hydrogens. The hydrogens will lose electron density and become more positive creating a polar molecule. Two polar molecules will have a force of attraction between the opposite poles. HBB is not the same thing as Dipole moments. HBB occurs between polar molecules and dipole moments occur between nonpolar molecules.
