Kusiyana kwakukulu pakati pa barium ndi strontium ndikuti chitsulo cha barium chimakhala chogwira ntchito kwambiri kuposa chitsulo cha strontium.
Kodi Barium ndi chiyani?
Barium ndi mankhwala omwe ali ndi chizindikiro Ba ndi nambala ya atomiki 56. Amawoneka ngati chitsulo chotuwa chasiliva chokhala ndi utoto wotuwa wachikasu.Pokhala ndi okosijeni mumlengalenga, mawonekedwe oyera ngati silvery amazimiririka ndikupatsa mdima wandiweyani wokhala ndi okusayidi.Mankhwalawa amapezeka mu tebulo la periodic mu gulu 2 ndi nthawi 6 pansi pa zitsulo zamchere zamchere.Ndi chinthu cha s-block chokhala ndi kasinthidwe ka electron [Xe] 6s2.Ndiwolimba pa kutentha wokhazikika ndi kupanikizika.Ili ndi malo osungunuka kwambiri (1000 K) ndi malo otentha kwambiri (2118 K).Kachulukidwe ndi okwera kwambiri (pafupifupi 3.5 g/cm3).
Barium ndi strontium ndi mamembala awiri a gulu la alkaline earth metals (gulu 2) pa tebulo la periodic.Izi zili choncho chifukwa maatomu achitsulowa ali ndi kasinthidwe ka ma elekitironi a ns2.Ngakhale kuti ali m’gulu limodzi, amakhala a nyengo zosiyanasiyana, zomwe zimawapangitsa kukhala osiyana pang’ono ndi wina ndi mnzake muzochita zawo.
Zomwe zimachitika mwachilengedwe za barium zitha kufotokozedwa ngati zoyambirira, ndipo zimakhala ndi mawonekedwe amtundu wa cubic crystal.Komanso, barium ndi chinthu cha paramagnetic.Chofunika kwambiri, barium ili ndi kulemera kwake kocheperako komanso kutsika kwamagetsi kwapamwamba.Izi zili choncho chifukwa chitsulochi chimakhala chovuta kuchiyeretsa, zomwe zimapangitsa kuti zikhale zovuta kudziwa zambiri za katundu wake.Poganizira za reactivity yake yamankhwala, barium imakhala ndi reactivity yofanana ndi magnesium, calcium, ndi strontium.Komabe, barium imagwira ntchito kwambiri kuposa zitsulo izi.Mkhalidwe wabwinobwino wa okosijeni wa barium ndi +2.Posachedwapa, kafukufuku wapezanso mawonekedwe a +1 barium.Barium amatha kuchitapo kanthu ndi chalcogens mu mawonekedwe a exothermic reactions, kutulutsa mphamvu.Choncho, barium yachitsulo imasungidwa pansi pa mafuta kapena mumlengalenga.
Kodi Strontium ndi chiyani?
Strontium ndi mankhwala omwe ali ndi chizindikiro Sr ndi nambala ya atomiki 38. Ndizitsulo zamchere zamchere mu gulu 2 ndi nthawi 5 pa tebulo la periodic.Ndiwolimba pa kutentha wokhazikika ndi kupanikizika.Malo osungunuka a strontium ndi okwera (1050 K), ndipo malo otentha ndi okwera (1650 K).Kachulukidwe ake ndi okwera komanso.Ndi s block element yokhala ndi ma elekitironi kasinthidwe [Kr] 5s2.
Strontium imatha kufotokozedwa ngati chitsulo chasiliva cha divalent chokhala ndi utoto wotuwa wachikasu.The zimatha chitsulo ichi ndi wapakatikati pakati oyandikana mankhwala zinthu calcium ndi barium.Chitsulo ichi ndi chofewa kuposa calcium komanso cholimba kuposa barium.Mofananamo, kuchuluka kwa strontium kuli pakati pa calcium ndi barium.Pali ma allotropes atatu a strontium komanso.Chifukwa chake, mwachilengedwe amapezeka pazophatikiza pamodzi ndi zinthu zina monga strontianite ndi celestine.Komanso, tifunika kuisunga pansi pa ma hydrocarbons amadzimadzi monga mafuta amchere kapena palafini kuti tipewe oxidation.Komabe, chitsulo chatsopano cha strontium chimasintha msanga kukhala mtundu wachikasu chikakumana ndi mpweya chifukwa chopanga okusayidi.
Kodi pali kusiyana kotani pakati pa Barium ndi Strontium?
Barium ndi strontium ndizofunikira zitsulo zamchere zamchere mu gulu 2 la tebulo la periodic.Kusiyana kwakukulu pakati pa barium ndi strontium ndikuti chitsulo cha barium chimakhala chogwira ntchito kwambiri kuposa chitsulo cha strontium.Komanso, barium ndi yofewa kwambiri kuposa strontium.
