Le metal elula. Zeziphi iintsimbi ukukhanya?

Le metal yokuqala loo mntu uyaziwa, baba negolide, nobhedu nesilivere. Zazisetyenziswa kumaxesha amandulo. Ziziphi ezi izinto? Yeyiphi but is ilula?

ezimbiwa

Kuba ngqa abantu bafumanisa ukuba iintsimbi ukuba kufutshane kumphezulu. Kuqala ke nobhedu, igolide nesilivere, kamva kunye yi ithini, isinyithi, nobhedu kunye bakhokele. Ngophuhliso loluntu uluhlu kancinane lwandiswe. Okwangoku kukho malunga nama-94 iintsimbi.

Bona enezinto elula ukuba ulime conductivity ephakamileyo transfer nobushushu, ductility, hoxa nzini, abe ebuntsimbi ayenechaphothi isici. Kwindalo, ukuba afunyanwa rhoqo kwi ngokohlobo iikhompawundi ezahlukeneyo ores.

Kwi iimpawu iintsimbi yahlulwe ayoni, nonferrous kunye anqabileyo. Ukusebenzisa kwabo wahluliwe nsimbi, ukucocwa olwenziwa, alloying kunye nezinye processing. Iintsimbi eziyinxalenye eziphilayo zikhoyo olwandle.

Emzimbeni wethu, ukuba kumanani ezincinane, enza imisebenzi ebalulekileyo ebomini. Langoku isibindi lobhedu, calcium - kuphahla kunye amazinyo, sodium - xa kukho icytoplasm yeseli, intsimbi yinxalenye igazi imisipha wemagniziyam.

Le metal elula kunenye

Ezingqondweni zabantu abaninzi anamathela ngokoluvo isinyithi nje okunamandla, owomeleleyo enzima. Abanye babo ngokupheleleyo engafanelekanga ukuchaza. Kukho inani zesinyithi ukuba abe amandla eliphantsi isiqabu kwezi zinto ukuhamba. Ziyakwazi abhabhe phezu kwamanzi.

I-metal kunenye ehlabathini - Lithium. Bushushu, ukuxinana yayo sesiphantsi. Inika amanzi phantse kabini kwaye 0,533 grams ngamnye sentimitha cc. Ngenxa lexinene encinane, oko ndiyihlanganise ndiyidadise emanzini kunye separafini.

Lithium uqulathwe emanzini olwandle kunye noqweqwe eliphezulu zwekazi. Kukuninzi, intsimbi elula ekhoyo kwi into obalaseleyo Thorne-Zhitkova, nto leyo equka ingxilimbela ebomvu kunye supergiant.

Phantsi kweemeko eziqhelekileyo, lithium na ductile metal ubuhle oluthambileyo, ezithambileyo ukuze bonqanyulwa ngemela. Linyibilike at 181 degrees Celsius. Kuyinto ziyityhefu kwaye ngokubonakalayo esinxibelelana bume, ngoko alisetyenziswa uhlobo yayo enyulu.

aluminium

Emva lithium sisinyithi kunenye - aluminiyam, koko, oko ixesha elide kakhulu. Ngenxa ukusetyenziswa kakhulu kwiinkalo ezahlukahlukeneyo, wazakhela isihloko 'yenkcenkce kwinkulungwane XX ". Kulo neuron, umhlaba yena element wesithathu zixhaphakileyo phakathi iintsimbi bokuqala.

Aluminium has a isilivere-omhlophe, abe ductility ophezulu, kunye conductivity thermal. Kuyinto olukwazi zokubumba aluminium phantse kukhona. Amaninzi ukusetyenziswa kudibaniso nge wemagniziyam nangobhedu. aluminiyamu ezininzi yomelele kunentsimbi.

Aluminium ayikaqondwa iSADC xi umhlwa ngenxa ukuyilwa bhanya oxide. Yena amathumba kubushushu ka-2500 degrees Celsius. It is a paramagnetic obuthathaka. Uhlobo intsimbi equlethwe ngokohlobo iikhompawundi, igolide zayo enqabile kuphela kwezinye migodi mlilo.

iqhekeza ikhekhe

Mikrolattis - intsimbi elula wavelisa ngokuzenzela. Le ibandakanya umoya kwi 99,99% kwaye kulula kakhulu njengogwebu. Metal wadala zizazinzulu weYunivesithi California, ngo-2016 oko nokwazeka ngokusemthethweni kwaye sele adweliswe Guinness Book of Records.

Le mfihlelo ke abatyeshileyo engaqhelekanga kubume bayo efana thambo eziphilayo. Metal iseli ukuba zenziwe netyhubhu nickel-phosphorous. Yokuba zizinto ezingeyonene ngaphakathi, kwaye ubukhulu yabo izihlandlo eziliqela ngaphantsi kwe nonwele lomntu.

Nangona ubulula mikrolattis ekwaziyo withstanding imithwalo enzima ngcono ngaphezu iintsimbi zendalo. propati zingasetyenziswa ngokubanzi, omnye wabo - kukudala kukhanya okwenziwe.
