Why Is Chlorine A Gas At Room Temperature But Iodine Is A Solid, Since they are diatomic, they make a good model system of van der Waals dispersion forces.

Why Is Chlorine A Gas At Room Temperature But Iodine Is A Solid, 7 °C, meaning it transitions directly from solid to gas at this temperature. At STP, it is a solid. May 26, 2026 · Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. As iodine has a higher atomic number than chlorine, it also has more electrons in its electron shells. . Their group number only describes the number of electrons they have in their outer shell. Iodine has an electron configuration of [Kr]5s 2 4d 10 5p 5, with the seven electrons in the fifth and outermost The tendency toward gaseous behavior depends on weak intermolecular forces and high vapor pressure—properties clearly visible when comparing elements like iodine (a solid near room temp) to chlorine (a gas) or fluorine (a reactive gas). The difference in physical state between chlorine (gas) and iodine (solid) at room temperature is directly attributable to the difference in their molecular sizes. The halogens - fluorine, chlorine, bromine, and iodine - are in group 17 of the periodic table and are all diatomic molecules, X2, at room temperature.
