Umahluko ophambili phakathi kwe-Barium kunye neStrontium kukuba isinyithi se-barium sisanda ngakumbi kwi-strontium yentsimbi.
Yintoni inkulu?
I-Barium yindawo yekhemikhali enophawu lwe-ba kunye nenani leatomic 56. Ibonakala njenge-Silver-grey-grey tint ye-tint etyheli etyheli. Kwi-oxidation emoyeni, i-Siltery-imbonakalo emhlophe yaphela ngequbuliso ukuba inikezele nge-grey emnyama equka i-oxide. Eli nqaku lezikhemikhali lifumaneka kwitheyibhile yamaxesha eqela le-2 kunye nexesha le-6 phantsi kwe-Alkaline yomhlaba. Yinto ye-S-block enoqwalaselo lwe-elektroni [Xe] 6s2. Siqinile kubushushu obuqhelekileyo kunye noxinzelelo. Inomxholo ophezulu wokunyibilika (i-1000 k) kunye nendawo ebilayo ephezulu (2118 k). Ukuxinana kuphezulu kakhulu (malunga ne-3.5 g / cm3).
I-Barium kunye neStrontium ngamalungu amabini eqela le-Alkaline yomhlaba (Iqela 2) letafile yexesha. Kungenxa yokuba iiathom zentsimbi zinoluvo lwe-Eletron ye-NS2. Nangona bekwiqela elinye, bamaxesha ahlukeneyo, nto leyo ebangela ukuba bahluke kancinane kwezinye.
Ukwenzeka kwendalo kwe-Barium kunokuchazwa njengendawo elungileyo, kwaye inomzimba ogxile kwikristali yekrinta. Ngapha koko, i-Barium yinto yeparamagnetic. Okubaluleke ngakumbi, ibarium inomzimba ophakathi kunye nokuqhutywa kombane okuphezulu. Kungenxa yokuba esi sinyithi kunzima ukuhlambulula, oko kwenza ukuba kube nzima ukufumana uninzi lwezinto zayo. Xa ujonga ukuvela kwayo imichiza, i-Barium inomsebenzi wokuphinda usebenze kwi-magnesium, i-calcium, kunye neStrontium. Nangona kunjalo, i-Barium isebenza ngakumbi kunezi ntsimbi. Imeko yesiqhelo ye-Oxiidation ye-Barium ngu- +2. Kutshanje, izifundo zophando zifumene ifom ye-A +1. I-Barium ingasabela nge-chalcogens ngohlobo lwezinto zokuphendula, ukukhulula amandla. Ke ngoko, ibharitic ye-metrium igcinwe phantsi kweoyile okanye kwindawo ye-intert.
Yintoni iStrontium?
I-strontium yindawo yekhemikhali enesimboli kunye nenombolo yeatomic 38. Yintsimbi ye-alkali ene-altine kwiqela 2 kunye nexesha le-5 letafile yexesha. Siqinile kubushushu obuqhelekileyo kunye noxinzelelo. Indawo yokunyibilika yeStrontium iphezulu (i-1050 k), kwaye inqaku elibilayo liphezulu (1650 k). Ukuxinana kwayo kuphezulu. Yindawo ye-SPRIBLOST enoqwalaselo lwe-elektroni [kr] 5s2.
I-strontium inokuchazwa njengentsimbi yesilivere ene-pint enetyheli etyheli. Iipropathi zentsimbi ziphakathi phakathi kweekhemikhali zekhemikhali ezingabamelwane kunye nebarium. Esi sinyithi sithambile kune-calcium kwaye inzima kuneqonga. Ngokufanayo, ukuxinana kweStrontium kuphakathi phakathi kwe-calcium kunye nebarium. Zintathu ii-lalrotriums zestrontium njenge.strontium zibonisa ukwenziwa okuphezulu kwamanzi kunye neoksijini. Ke ngoko, ngokwemvelo iyenzeka kuphela kwi-complets kuphela ecaleni kwezinto ezinjengeStrontianite kunye ne-nionarine. Ngapha koko, kufuneka siyigcine phantsi kwe-hydrocarbons enamanzi njengeoyile yezimbiwa okanye i-kerosene ukuthintela i-oxidation. Nangona kunjalo, i-strontium entsha yentsimbi ijika iguqukele kumbala ophuzi xa ityhilwe ngumoya ngenxa yokuqulunqa i-oxide.
Yintoni umahluko phakathi kwebarium kunye nestrontium?
I-Barium kunye neStrontium zibalulekile emhlabeni ze-alkaline zomhlaba kwiQela le-2 letafile yexesha. Umahluko ophambili phakathi kwe-Barium kunye neStrontium kukuba isinyithi se-barium sisanda ngakumbi kwi-strontium yentsimbi. Ngaphezu koko, ibanga lingathanga kakhulu kuneStrontium.
