Who is iodine named after

Among the more common, everyday uses of iodine are the following: in halogen lamps, as a salt additive to prevent goiter , and in ink pigments. Tincture of iodine is used as a topical antiseptic to kill bacteria.

Silver iodide is used in the preparation of some photographic films. Peter J. Stang is distinguished professor of chemistry and dean of the College of Science at the University of Utah.

Schleyer Richard R. Whitesides Robert L. A radioactive isotope of iodine, iodine, is used to treat some diseases of the thyroid gland. Care should be taken in handling and using iodine. It can burn the skin and damage the eyes and mucous membranes. Pure iodine is poisonous if ingested. Estimated Crustal Abundance : 4. Number of Stable Isotopes : 1 View all isotope data.

Iodine Previous Isotopes Next. The maximum allowable concentration in air when working with iodine is just 1 mg m All iodides are toxic if taken in excess. Iodine is one of the radionuclides involved in atmospheric testing of nuclear weapons, which began in , with a US test, and ended in with a Chinese test. It is among the long-lived radionuclides that have produced and will continue to produce increased cancers risk for decades and centuries to come.

Iodine increases the risk of cancer and possibly other diseases of the thyroid and those caused by thyroid hormonal deficiency. Iodine in air can combine with water particles and precipitate into water or soils.

Iodine in soils will combine with organic matter and remain in the same place for a long time. Plants that grow on these soils may absorb iodine. Cattle and other animals will absorb iodine when they eat these plants. Iodine in surface water will vaporize and re-enter the air as a result.

Humans also add iodine gas to the air, by burning coal or fuel oil for energy. But the amount of iodine that enters the air through human activity is fairly small compared to the amount that vaporizes from the oceans. Iodine may be radioactive. The radioactive isotopes are formed naturally during chemical reactions in the atmosphere.

Most radioactive isotopes of iodine have very short half-lives and will reshape into stable iodine compounds quickly. However, there is one radioactive form of iodine that has a half-live of millions of years and that is seriously harmful to the environment.

This isotope enters the air from nuclear power plants, where it is formed during uranium and plutonium processing. Accidents in nuclear power plants have caused the release of large amounts of radioactive iodine into air. Read more on iodine in water. Back to the periodic table of elements.
