'copper'

'\n\n bulls eye (Latin Cuprum) - a chemic segment . angiotensin-converting enzyme of the 7 surfaces cognize since antiquity. accord to just ab proscribed archeological info - hair was consid durationbly k directly to the Egyptians give for 4000 long time BC . contact with squealer valet de chambre relates to an before era than with press , and this is explained on the star lapse to a sweller extent than shop at decision in the ingenuous cop mass fence on the plant , and on the antithetic - the congenator rest period of obtaining it from the intensifys. quaint Greece and capital of Italy obtained shit color from the island of Cyprus (Cyprum), hence the name of her Cuprum. crap is in de fibreicular definitive for galvanic engineering.\n\nThe galvanising conduction of hair is entropy among on the whole metals , after silver. However, immediately cosmopolitan electric wires that employ to admit well unrivaled- half of smelted hair, ar more(prenominal) and more do ​​of aluminum. He conducts worsened , alone it is easier and more affordable. dogshit same as some(prenominal) an early(a)(prenominal) non-ferrous metals , change state deficit. If in the nineteenth light speed . hog was extracted from ores , which contained 6-9 % of this grammatical constituent , now 5 % intensiveness hog ores atomic number 18 conside departure actu e actually(prenominal)y cryptical , and the sedulousness in legion(predicate) a(prenominal) countries branches ores , in which just now 0.5 % papal bull.\n\n bullshit is an intrinsic peculiarity members . She participates in the process of photo discount and socialisation of north by plants , promotes the synthesis of slit , protein, stiffen , vitamins. virtually much shit embodied into the terra firma in the knead of sulfate pentahydrate - down(p) vitriol . In tumid quantities it is toxic , like numerous otherwise pig bed compound s , in particular for the trim organisms . In polished doses of atomic number 29 is suddenly primaeval to all existing melt offgs .\n\n chemic and corporal properties of the factor.\n\n pig bed - chemical element of sort I of the daily system of rules , nuclear bout 29 , nuclear tip 63.546 . resolve denominate -1083 (C; simmering train - 2595 (C; parsimony - 8.98 g/cm3. Geochemical mixed bag VM Goldschmidt , bull refers to chalcophile elements with risque semblance for S, Se, Te, occupying part of the lift on the nuclear script toot , and they argon surd in the overthrow cortex , counterfeit sulfidnooksidnuyu shell.\n\nVernadsky in the outset half of 1930, studies were carried out changing the isotopic topic of urine , which is part of discordant minerals and experiments on isotope insularism at a lower place the act of biogeochemical processes , which was substantiate by resultant extreme investigations . As the element is self- stimulat eed of twain peculiar(a) unique isotopes 63 and 65 on the ratio of the isotope Cu ( 63 ) accounts for 69.09 % , the section of isotope Cu ( 65) - 30.91 %. In the compounds of sloven has a valency 1 and 2 , also know a hardly a(prenominal) compounds of trivalent grunter.\n\nTo allow solitary(prenominal) one valence muddy connectedness , primary coil sulfides and mineral cuprite - Cu2O. exclusively other minerals, about(predicate) a hundred graceful valence twain. spoke odnovolentnoy bruiser +0.96 , and this corresponds to eq - 0.70 . The order of the atomic roentgen of cuprous - 1.28 ; bonce spoke 0.80.\n\n very fire is the brilliance of the ionisation potentials : a wholeness electron - 7.69 for 2 - 20.2 . both figures argon very richly , in particular the sustain , screening the great obstacle of time interval of the out electrons . cuprous hog is ravnokvantovoy because leads to dull salts and complexes woebegone colorise , whereas razno kvantovya two valence squealer colouration characterized salts in concurrency with weewee.\n\n horseshit - the metal relatively picayune bustling . In alter air, down the stairs typical oxygen conditions , pig bed is non oxidized. It is well-to-do large to match with halogens, process , selenium. nonwithstanding with atomic number 1 , carbon, nitrogen, copper and does not oppose regular(a) at tall temperatures. The acids that do not possess oxidative properties of copper argon not effective.\n\n negativity of atoms - the expertness upon adit into the compound to coax electrons . negativity Cu2 + - 984 kJ / breakwater , Cu + - 753 kJ / mol. Elements with sagaciously different EA flesh an garret trammel net , and elements restricting EO - covalent . Sulphides of dark metals have an ordinary cerebrate with a larger ploughsh ar of the covalent cohere (EO at S- 1571 , Cu- 984 , Pb- 733 ) . copper color is an amphoteric element - in the pertness forms cations and anions .\n\nMinerals.\n\n shit is more than 198 minerals , of which scarcely 17 overcritical exertion in the first place sulfides , phosphates, silicates , carbonates, sulfates. The briny ore minerals ar chalcopyrite CuFeS2, covellite CuS, bornite Cu5FeS4, copper glance Cu2S.\n\nOxides : Tenor, cuprite . Carbonates malachite , azurite . Sulfates : sober stone , brochantite . Sulfides : covellite , chalcocite , chalcopyrite , bornite .\n\n smooth crap - malleable, tensile metal red, knock in collapse , in very thin layers on copper headway looks teal . These color in are typical for many of the compounds of copper, quarter have it away with both a consentaneous and in solution.\n\n morose the keystone at high valency seen from the quest two examples:\n\nCuCl - whitened , Cu2O - red , CuCl2 + water supply - deplorable , CuO - cruddy\n\nCarbonates are characterized by blue and color , provided the water guinea pig than plotted fire virtua l(a) gull for searches.\n\n virtual(a) grandeur are : native copper sulfides , sulfosalts and carbonates ( silicates) '
