NettetHistorie. Indium ble oppdaget av de tyske kjemikerne Ferdinand Reich og Theodor Richter ved Bergakademie Freiberg i 1863. De lette etter thallium i mineralet sinkblende ved hjelp av spektrografi, da de i tillegg til spektrallinjene fra thallium fant en linje i den indigofargede delen av spekteret.Denne linjen stammet fra indium, og ga også navnet til det nye … Nettet21. aug. 2024 · Indium has the chemical symbol In and the atomic number 49. It has the electron configuration [Kr] 2s 2 2p1 and may adopt the +1 or +3 oxidation state; however, the +3 state is more common. It is a soft, malleable metal that is similar to gallium. Indium forms InAs, which is found in photoconductors in optical instruments.

Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Indium has a melting point higher than sodium … Se mer Physical Indium is a silvery-white, highly ductile post-transition metal with a bright luster. It is so soft (Mohs hardness 1.2) that like sodium, it can be cut with a knife. It also leaves a visible line on paper. … Se mer In 1863, the German chemists Ferdinand Reich and Hieronymous Theodor Richter were testing ores from the mines around Freiberg, Saxony. … Se mer Indium is produced exclusively as a by-product during the processing of the ores of other metals. Its main source material are sulfidic zinc ores, where it is mostly hosted by sphalerite. Minor amounts are probably also extracted from sulfidic copper ores. During the Se mer Indium has no metabolic role in any organism. In a similar way to aluminium salts, indium(III) ions can be toxic to the kidney when given by … Se mer Indium(III) Indium(III) oxide, In2O3, forms when indium metal is burned in air or when the hydroxide or nitrate is heated. In2O3 adopts a structure like alumina and is amphoteric, that is able to react with both acids and bases. … Se mer Indium is created by the long-lasting (up to thousands of years) s-process (slow neutron capture) in low-to-medium-mass stars (range in mass between 0.6 and 10 solar masses). When a silver-109 atom captures a neutron, it transmutes into silver-110, which then … Se mer In 1924, indium was found to have a valued property of stabilizing non-ferrous metals, and that became the first significant use for the … Se mer
