Because of the bright blue lines in its emission spectrum

this is due to its extremely limited and expensive production

Because it is not naturally found on earth in its elemental form

Iodine Element Cube Martian Meteorite and is the lightest radioactiveIodine is a halogen within the atomic number 53. Its symbol is I. Iodine is an essential ion in the body and helps the thyroid produce specific hormones. Although it is a metallic solid at room temperature it forms a brilliant purple gas when heat is applied to it.
