Ni irihe tandukaniro riri hagati ya Barium na Strontium?

Itandukaniro ryibanze hagati ya barium na strontium nuko icyuma cya barium gikora cyane kuruta icyuma cya strontium.

Barium ni iki?

Barium ni ikintu cyimiti ifite ikimenyetso Ba na numero ya atome 56. Bigaragara nkicyuma cya silver-cyera gifite ibara ry'umuhondo ryijimye.Iyo okiside mu kirere, isura ya silver-yera igaragara gitunguranye kugirango itange ibara ryijimye ryijimye rigizwe na oxyde.Iyi miti iboneka mumeza yigihe cyitsinda rya 2 nigihe cya 6 munsi yubutaka bwa alkaline.Nibintu s-guhagarika hamwe nibikoresho bya electron [Xe] 6s2.Nibikomeye kubushyuhe busanzwe nigitutu.Ifite ingingo yo gushonga (1000 K) hamwe no guteka cyane (2118 K).Ubucucike buri hejuru cyane (hafi 3,5 g / cm3).

Barium na strontium ni babiri mubagize itsinda rya alkaline yisi (itsinda rya 2) kumeza yigihe.Ni ukubera ko atome zicyuma zifite ns2 ya electron.Nubwo bari mu itsinda rimwe, ni mubihe bitandukanye, bigatuma batandukana gato hagati yabo mumitungo yabo.

Ibintu bisanzwe bibaho bya bariyumu bishobora gusobanurwa nkibisanzwe, kandi bifite umubiri ushingiye ku mubiri wa kirisiti.Byongeye kandi, barium ni paramagnetic.Icy'ingenzi cyane, barium ifite uburemere bwihariye buringaniye hamwe nu mashanyarazi menshi.Ni ukubera ko iki cyuma kitoroshye kucyisukura, bigatuma bigorana kumenya byinshi mubiranga.Iyo usuzumye imiti ikora, barium ifite reaction isa na magnesium, calcium, na strontium.Ariko, barium irakora cyane kuruta ibyo byuma.Imiterere isanzwe ya okiside ya barium ni +2.Vuba aha, ubushakashatsi bwubushakashatsi bwabonye form ya +1 barium nayo.Barium irashobora kwitwara hamwe na chalcogène muburyo bwa exothermic reaction, ikarekura ingufu.Kubwibyo, metarique barium ibikwa munsi yamavuta cyangwa mukirere cya inert.

Strontium ni iki?

Strontium nikintu cyimiti gifite ikimenyetso Sr numubare wa atome 38. Nicyuma cyisi ya alkaline mumatsinda ya 2 nigihe cya 5 cyameza yigihe.Nibikomeye kubushyuhe busanzwe nigitutu.Ingingo yo gushonga ya strontium ni ndende (1050 K), naho aho gutekera nabyo ni hejuru (1650 K).Ubucucike bwabwo buri hejuru.Nibintu byahagaritswe hamwe nibikoresho bya electron [Kr] 5s2.

Strontium irashobora gusobanurwa nkicyuma gisa na feza gifite ibara ry'umuhondo ryijimye.Ibiranga iki cyuma kiri hagati yimiti ituranye ya calcium na barium.Iki cyuma cyoroshye kuruta calcium kandi kirakomeye kuruta barium.Muri ubwo buryo, ubucucike bwa strontium buri hagati ya calcium na barium.Hano hari allotropes eshatu za strontium.Strontium yerekana reaction nyinshi hamwe namazi na ogisijeni.Kubwibyo, mubisanzwe bibaho gusa mubice hamwe nibindi bintu nka strontianite na celestine.Byongeye kandi, dukeneye kubika munsi ya hydrocarbone yamazi nkamavuta yubutare cyangwa kerosene kugirango twirinde okiside.Nyamara, icyuma gishya cya strontium gihinduka ibara ryumuhondo iyo gihuye numwuka kubera imiterere ya oxyde.

Ni irihe tandukaniro riri hagati ya Barium na Strontium?

Barium na strontium nibyingenzi byingenzi bya alkaline yisi mumatsinda ya 2 yimeza yigihe.Itandukaniro ryibanze hagati ya barium na strontium nuko icyuma cya barium gikora cyane kuruta icyuma cya strontium.Byongeye kandi, barium igereranije yoroshye kuruta strontium.
