Americium(III) iodide | AmI3-3 | CID 101946332 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. This medical application is however obsolete. Experts have also warned that exposure to the toxic element may damage the lungs and thyroid glands. Our americium page has over 115 facts that span 47 different quantities. An atom of Americium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Americium. It can be lowered to 3–5 kg with a metal reflector and should become even smaller with a water reflector. Physical Properties. The main civilian use of plutonium is in breeder reactors and it may also be used as fissionable material in thermal reactors. They crystallize in the rock-salt lattice. Several americium compounds have been made and these are generally coloured - for example, the chloride is pink. Several americium compounds have been made and these are generally coloured - for example, the chloride is pink. Americium ’s behavior in the environment cannot be isolated from that of plutonium as a precursor of 241 Am. It is a transuranic element and is highly radioactive. It is less dense than its immediate neighbouring elements. Americium (VI) is precipitated with sodium acetate to produce the hydrate, NaAmO2 (C2H3O2)3 xH2O. A team of scientists in Israel has developed a concept that could serve as a future power source for space vehicles and other space-based applications such as the International Space Station. Know everything about Americium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure. Highlight all Match case. Compared to the alternative optical smoke detector, the ionization smoke detector is cheaper and can detect particles which are too small to produce significant light scattering; however, it is more prone to false alarms.

It is a highly radioactive element. Areas covered include atomic structure, physical properties, atomic interaction, thermodynamics, identification, atomic size, crystal structure, history, and nomenclature. Americium … 1961. A new determination of the heat of solution of americum metal and the heat of formation of various americium ions and compounds. Francis, in Radionuclide Behaviour in the Natural Environment, 2012. [105], One more proposal which utilizes the high nuclear fission rate of 242mAm is a nuclear battery. PHYSICAL, CHEMICAL, AND RADIOLOGICAL PROPERTIES Americium is a silvery, ductile, very maleable, non-magnetic metal. [72], Oxyhalides of americium in the form AmVIO2X2, AmVO2X, AmIVOX2 and AmIIIOX can be obtained by reacting the corresponding americium halide with oxygen or Sb2O3, and AmOCl can also be produced by vapor phase hydrolysis:[68], The known chalcogenides of americium include the sulfide AmS2,[73] selenides AmSe2 and Am3Se4,[73][74] and tellurides Am2Te3 and AmTe2. Some of these BTP-type complexes selectively interact with americium and therefore are useful in its selective separation from lanthanides and another actinides. The number of electrons in each of Americium's shells is 2, 8, 18, 32, 25, 8, 2 and its electron configuration is [Rn] 5f 7 7s 2. History. Such low-power reactors would be relatively safe to use as neutron sources for radiation therapy in hospitals. Its salts are rose coloured and it has a sharp adsorption spectra in visible, ultraviolet and infrared light. In the nuclear reactor, 242Am is also up-converted by neutron capture to 243Am and 244Am, which transforms by β-decay to 244Cm: Irradiation of 241Am by 12C or 22Ne ions yields the isotopes 247Es (einsteinium) or 260Db (dubnium), respectively. Malleable or Not Malleable? Physical Properties of Americium. Americium, basic physical and chemical properties of the element. With an atomic number of 95, americium is an actinide metal that was made and discovered in 1940's. Americium from atmospheric nuclear weapons tests may remain in the atmosphere for decades travelling all around the world and settling slowly to earth. Physical and chemical properties of Americium: general data, thermal properties, ionization energies, isotopes, reduction potentials, abundance of elements, crystallographic data. In nature, it is found in traces of most of the Uranium ores. Previous. [97][98][99][100], As 241Am has a roughly similar half-life to 238Pu (432.2 years vs. 87 years), it has been proposed as an active element of radioisotope thermoelectric generators, for example in spacecraft.
