In the gaseous state, iodine molecules exist as diatomic molecules (I2) that are more spatially separated, allowing for greater bond lengths due to reduced intermolecular interactions. In contrast, in the solid state, iodine atoms are packed closely together in a crystalline arrangement, which can lead to increased interactions between neighboring molecules, effectively shortening the bond length. Thus, the bond length in the gaseous state is greater due to less steric hindrance and weaker interactions compared to the solid state.
Iodine molecule has covalent bonds.
Deposition examples: gaseous iodine, and the water in snow clouds.
In the transition from solid iodine (I2(s)) to gaseous iodine (I2(g)), entropy increases. This is because the gaseous state has a higher degree of disorder and greater molecular motion compared to the solid state, where the molecules are more closely packed and organized. The increase in volume and freedom of movement in the gas phase contributes to this rise in entropy.
In the reaction ( \text{I}_2(s) \rightarrow \text{I}_2(g) ), the entropy increases. This is because the transition from solid iodine to gaseous iodine involves a change from a more ordered state (solid) to a more disordered state (gas), where the molecules have greater freedom of movement. As a result, the number of possible microstates increases, leading to higher entropy in the gaseous phase compared to the solid phase.
When iodine sublimes, it transitions from a solid state directly to a gaseous state without passing through a liquid phase. This process requires energy, known as the enthalpy of sublimation, which is absorbed from the surroundings. As the iodine molecules gain energy, they overcome the intermolecular forces holding them together in the solid form, resulting in the formation of gaseous iodine. This absorption of energy leads to a cooling effect in the surrounding environment.
In the solid state, iodine molecules are held together by intermolecular forces, which create a larger average distance between the atoms compared to when they are in the gaseous state and are free to move independently of one another. The intermolecular forces in the solid, such as Van der Waals forces, result in a longer bond distance between the iodine atoms.
Iodine molecule has covalent bonds.
No, iodine is a dark purple, shiny solid at room temperature. It has a characteristic metallic luster and can sublimate directly from a solid to a gaseous state.
Bluish-Black Solid, and Purple in Gaseous state

No, iodine is not a conductor in its molten state. Iodine is a non-metal and does not conduct electricity, whether in solid, liquid or gaseous state.
Iodine typically has a shiny appearance, especially in its solid crystalline form. However, when iodine is in a gaseous state, it appears as a purple vapor.

After the iodine is in gaseous form, contain and cap it off with an iced container to recollect it and turn it back into a solid by allowing the gas to rest. The temperature then has to be below 113.5°C in order to solidify.
think in the gaseous phase there are other forces acting atoms of iodine like inter moleculer forces due to wich bond distance increases. in case of gasous state there are no other force acting on the molecule of iodine axcept electrostatic force between two atoms of iodine . so in case of gase elctrostatic force is more than in the case of solid..
Entropy increases in the reaction.
