Iodine. Iodine is a non-metallic, dark-gray/purple-black, lustrous, solid element. Iodine is the most electropositive halogen and the least reactive of the halogens even if it can still form compounds with many elements. Iodine sublime easily on heating to give a purple vapour.

Iodine has 53 protons and 53 electrons (because it has no charge the number of protons equals the number of electrons). Iodine-131 has 131 protons and neutrons. Iodine-131 has 131 minus 53 protons = 78 neutrons.

like many ionic substances, it could under the right conditions of temperature exist as a vapor consisting of separate molecules of lead iodide, and since it is non linear molecule, Pb (II) iodide has a dipole moment and therefore it would be polar.

At slightly elevated temperatures, the halogens bromine (Br2) and iodine (I2) also form diatomic gases. All halogens have been observed as diatomic molecules, except for astatine and tennessine, which are uncertain.

The characteristic of a pure substance is that it only contains atoms of only one kind. It has fixed physical and chemical properties, for example, melting point, boiling point, density, solubility, etc.

Iodide ions are strong reducing agents. Therefore, Copper (II) Iodide reduces to insoluble copper (I) iodide. ... CuI is not stable, so it doesn't exist in solution. It isn't stable because of electrochem and the solubility.

Iodine has high vapour pressure and when the eluted TLC plate is kept in iodine chamber the plate becomes saturated with iodine vapour and turn light brown. The compound spot will appear as a dark brown spot in the TLC plate. Iodine has a high affinity for unsaturated and aromatic compounds.

Iodine is a mineral found in some foods. The body needs iodine to make thyroid hormones. These hormones control the body's metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy.
