According to the source I found on the Web: "Of the halogens, fluorine has the highest crustal abundance (544 mg/kg) while iodine has the lowest (0.25 mg/kg), however, chlorine is by far the most abundant halogen in the cosmos."
It's fluorine if you're only interested in the Earth's crust, or chlorine if you're interested in the whole solar system or an even wider field than that.
