![]() ![]() In addition to the Earth’s crust, this element is in seawater. Out of the halogen family, iodine is the least abundant. KI acts to decrease the vapor pressure and to dilute iodine to make it safer. More specifically, this element reacts well with solutions containing potassium iodide (KI + I 2 → KI 3). ![]() However, it reacts oppositely towards aqueous solutions of iodide, where it is very soluble. Out of the halogen family, iodine is the least soluble in water, with a solubility value of 0.03 grams per 100 grams of water. Still, it has the greatest reducing strength and readily gains electrons from other atoms. However, compared to its family members, iodine is relatively less reactive. All halogens are highly electronegative and very reactive. The element iodine belongs to the halogen family, along with fluorine, chlorine, bromine, and astatine. The iodine atom has an electron configuration of 4d 105s 25p 5, or 1s 22s 22p 63s 23p 63d 104s 24p 64d 105s 25p 5 Iodine vs Other Halogens Its aqueous chemistry is similar to bromine’s. The element iodine lies below bromine, above astatine, to the right of tellurium, and to the left of xenon. Iodine, with atomic symbol I, is a nonmetal that lies in group 17 of the periodic table, the halogens. From 1994 to 2000, worldwide iodine production increased from 13,726 tons to 18,993 tons.The other radioactive isotopes change to their non-radioactive form in just seconds to days. Iodine-129 changes from radioactive form to nonradioactive over the span of millions of years.It is put into medicine to regulate the thyroid gland, treat goiter, treat thyroid cancer, and locate tumors. Iodine-131 is an important radioactive isotope.Unlike pure iodine, it exists by itself in nature. The only naturally occurring isotope of iodine is iodine-127. ![]() Seaweed in particular contains high concentrations of the element. More iodine is found in the ocean than the Earth’s crust.The addition of halogens improves this property. Non-polar drugs are able to easily transport across lipid membranes and tissue. ![]() This results in having a lipophilic drug, meaning it is not very water-soluble and non-polar. Halogen atoms are sometimes incorporated into lead drugs, which are the starting point of drug development.
