Kodi pali kusiyana kotani pakati pa barium ndi strontium?

Kusiyana kwakukulu pakati pa barium ndi strontium ndikuti barium chitsulo chimagwiritsidwa ntchito kwambiri kuposa chitsulo cha strontium.

Kodi Barium ndi chiyani?

Barium ndi chinthu china chokhala ndi chizindikiritso ba ndi atomiki nambala 56. Imawoneka ngati chitsulo chachitsulo chokhala ndi chisoti chachikasu. Pa makuti oxidation mlengalenga, mawonekedwe oyera oyera amakongoletsa mwadzidzidzi kumazirala kuti apatse imvi yakuda yopangidwa ndi oxide. Izi zimapezeka patebulo la nthawi yayitali mgulu 2 ndi nthawi 6 pansi pa zitsulo zapadziko lapansi. Ndi gawo la S-block ndi makonzedwe a elekitoni [XE] 6S2. Ndi yolimba kutentha ndi kukakamizidwa. Imakhala ndi malo osungunuka (1000 k) ndi malo owiritsa kwambiri (2118 k). Kuchulukitsa kumakhala kokwera kwambiri (pafupifupi 3.5 g / cm3).

Barlium ndi strontium ndi mamembala awiri a alkaline padziko lapansi (gulu 2) la tebulo la panthawiyo. Izi ndichifukwa ma atomu achitsulo awa ali ndi kusintha kwa NS2 Electron. Ngakhale ali m'gulu lomwelo, amakhala m'nthawi zosiyana, zomwe zimawapangitsa kukhala osiyana pang'ono ndi wina ndi mnzake m'malo awo.

Kupezeka kwachilengedwe kwa riyamu kumatha kufotokozedwa kuti ndi pri pri pri prixordal mawonekedwe a cubic. Komanso, barium ndi chinthu cha paramaginetic. Chofunika koposa, a Barium ali ndi kulemera kwakanthawi kochepa komanso mawonekedwe apamwamba apamwamba. Izi ndichifukwa choti chitsulo ichi ndizovuta kuyeretsa, zomwe zimapangitsa kuti zikhale zovuta kudziwa zambiri za zinthu zake. Mukamaganizira za kukhazikitsidwa ndi mankhwala ake, Barium ili ndi nkhuni yofanana ndi magnesium, calcium, ndi strontium. Komabe, barium ndi yopindulitsa kwambiri kuposa zitsulo zotere. Ma oxidation wamba a Barium ndi +2. Posachedwa, kafukufuku wapeza ma arbium a +1. Barium amatha kuchitira ndi ma alcogens mu mawonekedwe a exthermic zimachitika, kumasula mphamvu. Chifukwa chake, ma bacium salallic amasungidwa pansi pa mafuta kapena mumlengalenga.

Kodi strontium ndi chiyani?

Strontium ndi chinthu chopangidwa ndi chizindikiro cha SR komanso nambala ya atomiki 38. Ndi chitsulo cham'dziko cha anthu 2 ndi nthawi 5 ya tebulo la nthawi. Ndi yolimba kutentha ndi kukakamizidwa. Malo osungunuka a strontium ndi okwera (1050 k), ndipo malo owiritsa amakhalanso okwera (1650 k). Kuchulukitsa kwake kumakhalanso chimodzimodzi. Ndi gawo la slock ndi masinthidwe a elekitironi [KR] 5S2.

Stroteum ikhoza kufotokozedwa ngati chitsulo cha slovery chokhala ndi chingwe chachikasu. Zojambula za chitsulo ichi zimakhala zapakatikati pakati pa mankhwala oyandikana ndi calcium ndi barium. Zitsulo izi ndizofewa kuposa calcium komanso zolimba kuposa barium. Mofananamo, kuchuluka kwa strontium kuli pakati pa calcium ndi barum. Pali malo atatu a strontium monganso.Sstramium imawonetsa kukunja kwa madzi ndi mpweya. Chifukwa chake, mwachilengedwe zimachitika m'magulu ena ngati strontiote ndi ma cedestine. Kuphatikiza apo, tiyenera kuzisunga pansi pa hydrocarbons monga mafuta amchere kapena palafini kuti tipewe ma oxidation. Komabe, chitsulo chatsopano chimatembenukira mu mtundu wachikaso ukakhala ndi mpweya chifukwa cha mapangidwe a oxide.

Kodi pali kusiyana kotani pakati pa barium ndi strontium?

Barium ndi strontium ndi mankhwala ofunikira alkaline padziko lapansi pagulu lachiwiri. Kusiyana kwakukulu pakati pa barium ndi strontium ndikuti barium chitsulo chimagwiritsidwa ntchito kwambiri kuposa chitsulo cha strontium. Komanso, Barium ndiofalikira mofatsa kuposa strontium.
