Fluoride ions are smaller than chloride ions, which in turn are smaller than bromide and iodide ions. This means the ions can be packed closer together, and the (center to center) distance between the positive and negative ions is smaller. Dec 24, 2017 · The melting point of sodium iodide is 651 °C, and boiling point is 1304 °C. Sodium iodide is a deliquescent solid compound. This means it can absorb water vapor from the atmosphere and turn into a solution. Solid compound gets a brown color when exposed to air or light, due to the formation of iodine fumes.
