Zamchere lapansi zitsulo: kufotokoza mwachidule

Zamchere zitsulo lapansi zinthu za gulu lachiwiri la tebulo nthawi. Zikuphatikizapo zinthu monga calcium, magnesium, barium, beryllium, strontium, ndi rediamu. Dzina la gulu amasonyeza kuti kupereka anachita zamchere mu madzi.

Soda ndi zamchere lapansi zitsulo, kapena m'malo salt awo, zili ponseponse mu chirengedwe. Iwo amakhala ndi mchere. Kupatulapo ndi rediamu, amene amaona chinthu chosowa.

Onse zitsulo pamwamba ndi makhalidwe ena ofala amene amalola kuphatikiza iwo mu gulu limodzi.

zitsulo zamchere lapansi ndi katundu wawo thupi

Pafupifupi onse zinthu izi ndi zolimba grayish mtundu (osachepera m'mikhalidwe zachilendo ndipo yozungulira kutentha). Zodabwitsa ndizakuti, thupi katundu wa zitsulo soda ndi yosiyaniranapo - zinthu zimenezi ngakhale kugonjetsedwa ndithu, koma mosavuta poyera.

N'zochititsa chidwi ndi ndondomeko chiwerengero tebulo limakula ndi zitsulo zikuluzikulu monga osalimba. Mwachitsanzo, mu gulu uyu ali index wotsikitsitsa calcium, pamene Analandira osalimba ofanana ndi chitsulo.

Zamchere lapansi zitsulo: Mankhwala Katundu

Choyamba ndi Dziwani kuti mankhwala ntchito ukuwonjezeka malinga ndi chiwerengero siriyo ku gome nthawi. Mwachitsanzo, beryllium kugonjetsedwa ndithu amafotokozera. Mu anachita ndi mpweya ndi halogens chimadza kokha ndi Kutentha amphamvu. N'chimodzimodzinso ndi mankhwala enaake a pa. Koma kashiamu amatha oxidize pang'onopang'ono ngakhale firiji. Otsala atatu nthumwi gulu (Analandira, barium, ndi strontium) mofulumira anatani ndi mpweya mu mlengalenga ngakhale firiji. N'chifukwa chake kusunga zinthu izi, kuphimba wosanjikiza palafini.

oxides ntchito ndi hydroxides zitsulo izi ukuwonjezeka chimodzimodzi. Mwachitsanzo, beryllium hydroxide si sungunuka m'madzi ndipo amaona chinthu amphoteric, ndi barium hydroxide ndi soda mwachilungamo mphamvu.

zitsulo zamchere lapansi ndi makhalidwe awo mwachidule

Beryllium ndi zitsulo kugonjetsedwa kuwala imvi mtundu, kukhala kawopsedwe mkulu. mchitidwe woyamba wapezeka mu 1798 ndi sayansi Vauquelin. Mu chikhalidwe, pali beryllium mchere angapo, amene yotchuka kwambiri ndi izi: kulusolito, Phenacite, danalite ndi chrysoberyl. Zodabwitsa ndizakuti, ena isotopes wa beryllium ndi mkulu mpweya wa poizoni.

N'zochititsa chidwi kuti mitundu ina ya kulusolito zili zofunika miyala yamtengo wapatali miyala. Izi zikhoza monga emarodi, aquamarine ndi heliodor.

Beryllium ntchito zina kasakaniza wazitsulo chopopera. Mu nyukiliya makampani mphamvu , chinthu ichi ntchito m'mbuyo neutrons.

Kashiamu ndi mmodzi wa anthu otchuka kwambiri zitsulo zamchere lapansi. Mu mawonekedwe woyera ndi Zipangizo zofewa ndi silvery zoyera kulocha. Woyamba kashiamu woyera wakhala allocated mu 1808. Mu chikhalidwe, chinthu ichi chili mwa mawonekedwe a mchere monga nsangalabwi, miyala ndi gypsum. Kashiamu chimagwiritsidwa ntchito umisiri wamakono. Izo ntchito monga mankhwala mafuta gwero, komanso moto kugonjetsedwa zakuthupi. Ndi palibe chinsinsi chimene kashiamu pawiri ntchito popanga zipangizo nyumba ndi mankhwala.

mchitidwe umenewu ali chamoyo chilichonse wamoyo. Mwachidule, ndi udindo dongosolo minofu ndi mafupa.

Mankhwala enaake a ndi opepuka ndi mokwanira malleable zitsulo ndi khalidwe mtundu greyish. Mu maonekedwe ake angwiro iwo anali olekanitsidwa mu 1808, koma salt ake zinadziwika kale kwambiri. Mu zinthu zachilengedwe, mankhwala enaake a uli mu mchere monga magnesite, dolomite, carnallite, kieserite. Zodabwitsa ndizakuti, ndi mankhwala enaake a mchere amapereka madzi kuuma. A yaikulu ya mankhwala a mankhwala angapezeke m'nyanjamo.
