Yintoni Umahluko phakathi kweBarium kunye neStrontium?

Umahluko ophambili phakathi kwe-barium kunye ne-strontium kukuba isinyithi se-barium sisebenza kakhulu kwiikhemikhali kune-strontium metal.

Yintoni iBarium?

I-Barium yinto yekhemikhali enophawu u-Ba kunye nenombolo ye-athomu engu-56. Ibonakala njengentsimbi esiliva-grey kunye ne-tint ephuzi emthubi.Xa i-oxidation esemoyeni, inkangeleko emhlophe-esilivere ngokukhawuleza ithi shwaka inike umaleko omnyama ongwevu oquka ioxide.Le element yekhemikhali ifumaneka kwitheyibhile ye periodic kwiqela 2 kunye ne period 6 phantsi kwe alkaline earth metals.Yinto i-s-block element kunye noqwalaselo lwe-electron [Xe] 6s2.Iqinile kubushushu obuqhelekileyo kunye noxinzelelo.Inomgangatho ophezulu wokunyibilika (1000 K) kunye neqondo eliphezulu lokubilisa (2118 K).Uxinaniso luphezulu kakhulu ngokunjalo (malunga ne-3.5 g / cm3).

I-Barium kunye ne-strontium ngamalungu amabini eqela leentsimbi zomhlaba ze-alkaline (iqela lesi-2) kwitheyibhile yeperiodic.Oku kungenxa yokuba ezi athom zentsimbi zine-electron ns2 uqwalaselo.Nangona bekwiqela elinye, bangamaxesha ahlukeneyo, nto leyo ebenza bahluke kancinane omnye komnye ngokweempawu zabo.

Isehlo sendalo se-barium sinokuchazwa njenge-primordial, kwaye inomzimba ogxile kwi-cubic crystal structure.Ngaphezu koko, i-barium yinto yeparamagnetic.Okubaluleke ngakumbi, i-barium inobunzima obuthile obuphakathi kunye ne-conductivity ephezulu yombane.Oku kungenxa yokuba le ntsimbi inzima ukuyihlambulula, eyenza kube nzima ukufumana ezininzi iimpawu zayo.Xa kuqwalaselwa ukuphinda kusebenze kwayo imichiza, i-barium ine-reactivity efana ne-magnesium, i-calcium, kunye ne-strontium.Nangona kunjalo, i-barium isebenza ngakumbi kunezi zinyithi.Imeko eqhelekileyo ye-oxidation ye-barium yi +2.Kutshanje, izifundo zophando zifumene +1 ifomu ye-barium ngokunjalo.I-Barium inokusabela kunye ne-chalcogens ngendlela ye-exothermic reactions, ikhupha amandla.Ngoko ke, i-metallic barium igcinwa phantsi kweoli okanye kwindawo engasebenzi.

Yintoni iStrontium?

I-Strontium sisiqalelo sekhemikhali esinophawu Sr kunye nenombolo yeathomu engu-38. Yintsimbi yomhlaba yealkaline ekwiqela lesi-2 kunye nexesha lesi-5 letheyibhile yeperiodic.Iqinile kubushushu obuqhelekileyo kunye noxinzelelo.Indawo yokunyibilika yestrontium iphezulu (1050 K), kwaye indawo yokubilisa nayo iphezulu (1650 K).Ubuninzi bayo buphezulu ngokunjalo.Yinto s block element kunye noqwalaselo electron [Kr] 5s2.

I-Strontium inokuchazwa njengentsimbi edityanisiweyo eyisilivere ene-tint etyheli.Iipropathi zale ntsimbi ziphakathi phakathi kweekhemikhali ezingabamelwane ze-calcium kunye ne-barium.Le ntsimbi ithambile kune-calcium kwaye inzima kune-barium.Ngokufanayo, ubuninzi be-strontium buphakathi kwe-calcium kunye ne-barium.Kukho ii-allotropes ezintathu ze-strontium ngokunjalo.I-Strontium ibonisa ukusebenza kwakhona okuphezulu ngamanzi kunye ne-oxygen.Ke ngoko, yenzeka ngokwendalo kuphela kwiikhompawundi ecaleni kwezinye izinto ezifana nestrontianite kunye necelestine.Ngaphezu koko, kufuneka siyigcine phantsi kwee-hydrocarbons ezingamanzi ezifana neoyile yeminerali okanye i-kerosene ukuphepha i-oxidation.Nangona kunjalo, intsimbi entsha ye-strontium ijika ngokukhawuleza ibe ngumbala omthubi xa ibonakaliswe emoyeni ngenxa yokwakheka kwe-oxide.

Uthini Umahluko phakathi kweBarium kunye neStrontium?

I-Barium kunye ne-strontium zibalulekile iintsimbi zomhlaba zealkaline kwiqela lesi-2 letafile yeperiodikhi.Umahluko ophambili phakathi kwe-barium kunye ne-strontium kukuba isinyithi se-barium sisebenza kakhulu kwiikhemikhali kune-strontium metal.Ngaphezu koko, i-barium ithambile ngokuthelekiswa ne-strontium.
