Detailed explanation-3: -Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 °C (237 °F), and boils to a violet gas at 184 °C (363 °F).
Detailed explanation-4: -Hence, dry ice (CO2) is an example of a molecular solid.
Detailed explanation-5: -Iodine is an element with atomic symbol I, atomic number 53, and atomic weight of 126.90.
