He aha ka ʻokoʻa ma waena o Barium a me Strontium?

ʻO ka ʻokoʻa koʻikoʻi ma waena o ka barium a me ka strontium ʻo ia ka mea ʻoi aku ka ʻoi aku o ka metala barium ma mua o ka metala strontium.

He aha ka Barium?

ʻO ka Barium kahi mea kemika me ka hōʻailona Ba a me ka helu atomika 56. ʻIke ʻia ʻo ia ma ke ʻano he metala hina-hinahina me kahi ʻano melemele ʻeleʻele.Ma ka hoʻoheheʻe ʻia ʻana i ka ea, mae koke ke ʻano keʻokeʻo keʻokeʻo a hāʻawi i kahi papa hina ʻeleʻele i loko o ka oxide.Loaʻa kēia mea kemika ma ka papa ʻaina ma ka hui 2 a me ka manawa 6 ma lalo o nā metala honua alkaline.He mea s-block ia me ka hoʻonohonoho electron [Xe]6s2.He paʻa ia i ka mahana maʻamau a me ke kaomi.He wahi hehee kiʻekiʻe kona (1000 K) a me kahi helu hoʻolapalapa kiʻekiʻe (2118 K).He kiʻekiʻe loa ka mānoanoa (ma kahi o 3.5 g/cm3).

ʻO Barium a me strontium nā lālā ʻelua o ka hui metala honua alkaline (hui 2) o ka papaʻaina.No ka mea, loaʻa i kēia mau ʻātoma metala kahi hoʻonohonoho electron ns2.ʻOiai aia lākou i loko o ka pūʻulu hoʻokahi, pili lākou i nā manawa like ʻole, kahi e hoʻokaʻawale iki ai lākou mai kekahi i kekahi i kā lākou mau waiwai.

Hiki ke wehewehe ʻia ka hanana maoli o ka barium ma ke ʻano he primordial, a loaʻa iā ia kahi ʻano kristal cubic i hoʻokumu ʻia i ke kino.Eia kekahi, he mea paramagnetic ka barium.ʻO ka mea nui aku, loaʻa ka barium i ke kaumaha kikoʻī kūpono a me ka conductivity uila kiʻekiʻe.ʻO kēia no ka mea paʻakikī kēia metala e hoʻomaʻemaʻe, a he mea paʻakikī ke ʻike i ka hapa nui o kāna mau waiwai.I ka noʻonoʻo ʻana i kāna hana kemika, ua like ka barium me ka magnesium, calcium, a me strontium.Eia naʻe, ʻoi aku ka paʻakikī o ka barium ma mua o kēia mau metala.ʻO ke kūlana oxidation maʻamau o ka barium he +2.I kēia mau lā, ua loaʻa i nā noiʻi noiʻi kahi ʻano barium +1 pū kekahi.Hiki i ka Barium ke hana me nā chalcogens ma ke ʻano o nā hopena exothermic, hoʻokuʻu i ka ikehu.No laila, mālama ʻia ka barium metala ma lalo o ka aila a i ʻole i loko o kahi lewa inert.

He aha ka Strontium?

ʻO ka Strontium kahi mea kemika me ka hōʻailona Sr a me ka helu atomika 38. He metala honua alkaline ia ma ka hui 2 a me ka manawa 5 o ka papaʻaina.He paʻa ia i ka mahana maʻamau a me ke kaomi.He kiʻekiʻe ka helu heheʻe o ka strontium (1050 K), a he kiʻekiʻe hoʻi ka helu hoʻolapalapa (1650 K).Kiʻekiʻe nō hoʻi kona mānoanoa.He mea s poloka me ka hoʻonohonoho electron [Kr]5s2.

Hiki ke wehewehe ʻia ʻo Strontium ma ke ʻano he metala kala like ʻole me ka ʻulaʻula melemele.ʻO nā waiwai o kēia metala he waena ia ma waena o nā mea kemika kokoke i ka calcium a me ka barium.ʻOi aku ka palupalu o kēia metala ma mua o ka calcium a ʻoi aku ka paʻakikī ma mua o ka barium.Pēlā nō, aia ka nui o ka strontium ma waena o ka calcium a me ka barium.ʻEkolu allotropes o ka strontium pū kekahi. Hōʻike ka Strontium i ka reactivity kiʻekiʻe me ka wai a me ka oxygen.No laila, loaʻa maoli ia i loko o nā pūhui me nā mea ʻē aʻe e like me strontianite a me celestine.Eia kekahi, pono mākou e mālama iā ia ma lalo o nā hydrocarbons wai e like me ka aila mineral a i ʻole kerosene e pale aku i ka oxidation.Eia nō naʻe, huli koke ka metala strontium hou i kala melemele ke ʻike ʻia i ka ea ma muli o ka hoʻokumu ʻana o ka oxide.

He aha ka ʻokoʻa ma waena o Barium a me Strontium?

ʻO ka Barium a me ka strontium nā metala honua alkaline nui i ka hui 2 o ka papaʻaina.ʻO ka ʻokoʻa koʻikoʻi ma waena o ka barium a me ka strontium ʻo ia ka mea ʻoi aku ka ʻoi aku o ka metala barium ma mua o ka metala strontium.Eia kekahi, ʻoi aku ka palupalu o ka barium ma mua o ka strontium.
