What is the classification of iodine?
iodine (I), chemical element, a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
Is iodine a micronutrient?
Micronutrients, mostly iodine and selenium, are required for thyroid hormone synthesis and function. Iodine is an essential component of thyroid hormones and its deficiency is considered as the most common cause of preventable brain damage in the world.
How would you describe iodine?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states. Above 700 °C (1,300 °F), dissociation into iodine atoms becomes appreciable.
What is the systematic name for iodine?
Iodine | I2 – PubChem.
What are two ways to classify iodine?
Iodine is classified as a halogen — a subset of very chemically reactive elements (Group 17 on the periodic table) that exist in the environment as compounds rather than as pure elements. The other halogens include fluorine (F), chlorine (Cl), bromine (Br) and astatine (At).
What are 3 uses of iodine?
Today, iodine has many commercial uses. Iodide salts are used in pharmaceuticals and disinfectants, printing inks and dyes, catalysts, animal feed supplements and photographic chemicals. Iodine is also used to make polarising filters for LCD displays.
Do you need selenium with iodine?
Adequate intakes of both iodine and selenium are required for optimal thyroid function (1–3). Iodine is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), and deficiency will impair synthesis of these hormones.
Why is iodine important for humans?
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.
Is iodine dull or shiny?
Uses and properties A black, shiny, crystalline solid. When heated, iodine sublimes to form a purple vapour.
What is the chemical formula of iodine?
How is iodine related to other elements on the periodic table?
Iodine is the heaviest of the commonly occurring halogens. The halogens are in Group 17 (VIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Iodine’s chemical properties are similar to the lighter halogens above it, fluorine, chlorine, and bromine.
Are there any non radioactive forms of iodine?
There are non radioactive and radioactive forms of iodine. Iodine is used as a disinfectant for cleaning surfaces and storage containers and is used in skin soaps and bandages, and for purifying water.
What is the chemical formula for iodine PubChem?

What is the role of iodine in developmental biology?
The frog species Xenopus laevis has proven to be an ideal model organism for experimental study of the mechanisms of apoptosis and the role of iodine in developmental biology. Agents containing iodine can exert a differential effect upon different species in an agricultural system.
