Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
The process that is occurring as iodine solid is transformed into iodine vapour is SUBLIMATION.
Sublimation is the process by which a substance transformed from a solid state straight into a gaseous state without passing through the liquid state. Iodine is capable of undergoing sublimation process and this property is usually used to separate iodine from mixtures.<span />
