Is iodine a gas at 20 degrees?
Is iodine a gas at 20 degrees?
At a high enough temperature they will all be gases. It is only at temperatures between -7 °C and 59 °C that fluorine and chlorine are gases, bromine is a solid, and iodine is a solid.
What is the state of iodine at 25 degrees?
solids
State at room temperature Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.

Is iodine always I2?
There are two forms of iodine, elemental diatomic iodine (I2) and ionic monoatomic iodide (I-). I-, iodide, is essentially the only form found in nature. Iodide is the ionic state of iodine, occurring when iodine forms a salt with another element, such as potassium.
Is iodine a liquid at room temp?
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.
Is iodine solid at room temperature?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. Iodine has a moderate vapour pressure at room temperature and in an open vessel slowly sublimes to a deep violet vapour that is irritating to the eyes, nose, and throat.
At what temp does iodine freeze?
236.7°F (113.7°C)
Iodine/Melting point
Is Iodine a metal?
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance.
Is iodine same as iodide?
What is iodine? Also called iodide, iodine is a type of mineral that’s naturally found in the earth’s soil and ocean waters. Many salt water and plant-based foods contain iodine, and this mineral is most-widely available in iodized salt. It’s important to get enough iodine in the diet.
How much iodine is in sea salt?
Sea salt comes from a natural source and contains other minerals, but it does not contain iodine.
Is iodine a solid liquid or gas or gas?
Iodine. Iodine is a chemical element with symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a lustrous, purple-black non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.
What is the meaning of the word iodine?
Iodine is the fourth halogen, being a member of group 17 in the periodic table, below fluorine, chlorine, and bromine; it is the heaviest stable member of its group.
What is the oxidation state of iodine?
Iodine occurs in many oxidation states, including iodide (I−), iodate (IO−. 3), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. It is the heaviest essential mineral nutrient. Iodine is essential in the synthesis of thyroid hormones.
What is an example of iodine preparation?
Examples of such preparations include: Tincture of iodine: iodine in ethanol, or iodine and sodium iodide in a mixture of ethanol and water. Lugol’s iodine: iodine and iodide in water alone, forming mostly triiodide. Povidone iodine (an iodophor).
