Ndeupi Musiyano Pakati peBarium neStrontium?

Musiyano unokosha pakati pebarium uye strontium ndewekuti barium metal inonyanya kushandiswa kwemakemikari kupfuura strontium metal.

Chii chinonzi Barium?

Barium chinhu chemakemikari chine chiratidzo Ba uye nhamba yeatomu 56. Inoratidzika sesimbi ye-silvery-grey ine ruvara rweyero.Pakuiswa mumhepo, chitarisiko chichena-ruvara chinongoerekana chapera kuti chipe rima regrey layer rinosanganisira iyo oxide.Ichi chemakemikari chinhu chinowanikwa mu periodic tafura muboka 2 uye nguva 6 pasi pe alkaline pasi simbi.Icho chinhu che-s-block chine electron configuration [Xe] 6s2.Iyo yakasimba pane yakajairwa tembiricha uye kumanikidza.Iine nzvimbo yakakwirira yekunyunguduka (1000 K) uye nzvimbo yakakwirira yekuvira (2118 K).Density yakakwira zvakanyanya zvakare (inenge 3.5 g/cm3).

Barium uye strontium inhengo mbiri dze alkaline Earth metals boka (boka 2) reperiodic table.Izvi zvinodaro nekuti maatomu esimbi aya ane ns2 electron configuration.Kunyange zvazvo vari muboka rimwe chete, vari venguva dzakasiyana, izvo zvinoita kuti vasiyane zvishoma kubva kune mumwe nemumwe muzvinhu zvavo.

Chiitiko chemusikirwo chebarium chinogona kutsanangurwa sechinyakare, uye chine muviri-chepakati cubic crystal chimiro.Uyezve, barium chinhu paramagnetic chinhu.Zvinotonyanya kukosha, barium ine huremu hwepakati nepakati uye yakakwirira yemagetsi conductivity.Izvi zvinodaro nekuti simbi iyi inonetsa kuchenesa, izvo zvinoita kuti zviome kuona yakawanda yezvivakwa zvayo.Kana tichifunga nezvekuita kwayo kemikari, barium ine reactivity yakafanana nemagnesium, calcium, uye strontium.Zvisinei, barium inonyanya kushandiswa kupfuura simbi idzi.Yakajairika oxidation mamiriro e barium ndeye +2.Munguva pfupi yapfuura, zvidzidzo zvekutsvaga zvakawana +1 barium fomu zvakare.Barium inogona kuita nechalcogens nenzira ye exothermic reactions, kusunungura simba.Nokudaro, metallic barium inochengetwa pasi pemafuta kana mumhepo inert.

Chii chinonzi Strontium?

Strontium chinhu chemakemikari chine chiratidzo Sr uye nhamba yeatomu 38. Isimbi yepasi ine alkaline muboka 2 uye nguva 5 yeperiodic table.Iyo yakasimba pane yakajairwa tembiricha uye kumanikidza.Nzvimbo yekunyunguduka yestrontium yakakwira (1050 K), uye nzvimbo yekubikira yakakwira zvakare (1650 K).Density yaro yakakwira futi.I s block element ine electron configuration [Kr] 5s2.

Strontium inogona kutsanangurwa se divalent silvery simbi ine yakachenuruka yero tint.Zvinhu zvesimbi iyi zviri pakati nepakati pakati peakavakidzana makemikari zvinhu calcium uye barium.Iyi simbi yakapfava kupfuura calcium uye yakaoma kupfuura barium.Saizvozvo, kuwanda kwe strontium kuri pakati pe calcium ne barium.Kune matatu allotropes e strontium zvakare.Strontium inoratidza yakakwirira reactivity nemvura uye oksijeni.Naizvozvo, zvinowanzoitika mumakomboni pamwe chete nezvimwe zvinhu senge strontianite uye celestine.Zvakare, isu tinofanirwa kuichengeta pasi pemvura ma hydrocarbons senge mineral oil kana parafini kudzivirira oxidation.Nekudaro, simbi nyowani yestrontium inokurumidza kushanduka kuita yero ruvara kana yaiswa kumhepo nekuda kwekuumbwa kweoxide.

Ndeupi Musiyano Pakati peBarium neStrontium?

Barium uye strontium zvakakosha alkaline pasi simbi muboka 2 reperiodic table.Musiyano unokosha pakati pebarium uye strontium ndewekuti barium metal inonyanya kushandiswa kwemakemikari kupfuura strontium metal.Uyezve, barium yakapfava kupfuura strontium.
