Iodine - Iodine - Physical and chemical properties: 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.
The Physical properties of Iodine are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Iodine are as follows: What are the Physical Properties of ...
03/07/2019 Properties . Iodine has a melting point of 113.5°C, a boiling point of 184.35°C, a specific gravity of 4.93 for its solid state at 20°C, a gas density of 11.27 g/l, with a valence of 1, 3, 5, or 7. Iodine is a lustrous blue-black solid which volatizes at room temperature into a violet-blue gas with an irritating odor. Iodine forms compounds with many elements, but it is less reactive than ...
Physical Properties: Iodine is a solid diatomic non-metal that is very pungent in odor and a corrosive poison. Th density of iodine is 4.94 g/mL, which means it will sink in water. Chemical Properties: Iodine, I 2 is not reactive towards with oxygen, O 2, or nitrogen, N 2.
Iodine has a moderate vapor pressure at room temperature and in an open vessel slowly sublimes to a deep violet vapor that is irritating to the eyes, nose, and throat. This chapter tabulates the physical properties of iodine in solid, liquid and gas phases. Iodine dissolves easily in most organic solvents such as hexane, benzene, carbon tetrachloride, and chloroform owing to its lack of ...

Iodine-123 has excellent physical properties for an imaging agent. Like 131 I, its biochemical behavior is identical to that of stable iodine. Iodine-123 decays by electron capture, with a photon energy of 159 keV and a half-life of 13 hours. The gamma emission of 123 I allows excellent imaging (≈80% efficiency for a ½-inch-thick crystal) with low background activity. It provides ...

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. But its physical appearance is very different. It is a steel-gray solid that ...

The physical properties of molecular substances. Molecules are made of fixed numbers of atoms joined together by covalent bonds, and can range from the very small (even down to single atoms, as in the noble gases) to the very large (as in polymers, proteins or even DNA). The covalent bonds holding the molecules together are very strong, but these are largely irrelevant to the physical ...

An atom of Iodine in the gas phase, for example, gives off energy when it gains an electron to form an ion of Iodine. I + e – → I – – ∆H = Affinity = 295.2 kJ/mol To use electron affinities properly, it is essential to keep track of sign.
24/11/2020 The properties of iodine are used for a number of applications including as a dietary supplement and as a chemical in photography. As a supplement, iodine is usually added to salt since iodine isn't produced by the body. In the form of silver iodine, it is used to develop film. Other applications which utilize the properties of iodine include water purification, in which iodine tablets
