Alkaline duniya karafa: taƙaitaccen bayanin

Alkaline duniya karafa ne abubuwa da ciki na biyu kungiyar na lokaci-lokaci tebur. Wadannan sun hada da abubuwa kamar alli, magnesium, barium, beryllium, strontium, kuma radium. Sunan wannan kungiya ya nuna cewa su samar da wani alkaline dauki a ruwa.

Alkali da alkaline duniya karafa, ko wajen su salts, suna tartsatsi a cikin halitta. Suna wakilta ma'adanai. A togiya ne radium, wanda aka dauke a rare kashi.

Duk na sama karafa da wasu na kowa halaye da cewa ba da damar hada su a cikin daya kungiyar.

Alkaline duniya karafa da su jiki Properties

Kusan duk wadannan abubuwa ne da daskararru grayish launi (a kalla a karkashin al'ada yanayi da kuma yanayi zazzabi). Ba zato ba tsammani, jiki Properties na Alkali karafa ne dan kadan daban-daban - ko da yake wadannan abubuwa quite resistant, amma ana iya fallasa.

Abin sha'awa, da jerin lamba a tebur ke tsirarwa, kuma wani karfe bangaren matsayin yawa. Alal misali, a cikin wannan kungiya yana da mafi ƙasƙanci index of alli, yayin da radium yawa kama da baƙin ƙarfe.

Alkaline duniya karafa: Chemical Properties

Domin a farkon shi ne ya kamata a lura da cewa sinadaran aiki ƙaruwa bisa ga serial number na lokaci-lokaci tebur. Alal misali, beryllium ne quite resistant kashi. A dauki tare da oxygen da kuma halogens zo ne kawai da karfi dumama. Haka ya shafi cikin magnesium. Amma alli iya oxidize sannu a hankali ko da a dakin da zazzabi. Sauran uku wakilin kungiyar (radium, barium, kuma strontium) hanzari amsa tare da oxygen a cikin iska ko a dakin da zazzabi. Wannan shi ne dalilin da ya sa adana wadannan abubuwa, rufe Layer na kananzir.

Aiki oxides da hydroxides daga wadannan karafa ƙaruwa a cikin wannan hanya. Alal misali, beryllium hydroxide ba narkewa a cikin ruwa kuma an dauki wani amphoteric abu, kuma barium hydroxide ne fairly karfi Alkali.

Alkaline duniya karafa da su taƙaitaccen halaye

Beryllium ne da karfe resistant haske launin toka launi, da ciwon high yawan guba. Da farko kashi da aka gano a 1798 da wani sunadarai Vauquelin. A yanayi, akwai da dama beryllium ma'adanai, da abin da ya fi shahara ne da wadannan: lu'ulu'u, Phenacite, danalite da chrysoberyl. Ba zato ba tsammani, wasu isotopes na beryllium da high radioactivity.

Yana da ban sha'awa cewa wasu siffofin lu'ulu'u ne m ado da duwatsu. Wannan zai iya hada da zumurrudu, aquamarine, da heliodor.

Beryllium ake amfani da su yi wasu gami propellant. A cikin makaman nukiliya ikon masana'antu , wannan kashi da ake amfani da su rage neutrons.

Alli ne daya daga cikin shahararrun daga alkaline duniya karafa. A m nau'i shi ne mai taushi da kayan da silvery farin launi tint. A farko m alli da aka kasaftawa a 1808. A yanayi, wannan kashi ne ba a cikin nau'i na ma'adanai irin su marmara, farar ƙasa, kuma gypsum. Alli ne yadu a yi amfani da fasahar zamani. Ana amfani da a matsayin sinadaran man fetur source, kazalika da wuta resistant abu. Ba asiri da cewa alli fili amfani a yi na kayan gini da kuma magunguna.

Wannan kashi ne ma kunshe ne a cikin kowane mai rai kwayoyin. Amma, shi ne ke da alhakin musculoskeletal tsarin.

Magnesium ne hur kuma isasshe malleable karfe da halayyar greyish launi. A ta da tsarki form shi aka ware a 1808, amma da salts zama da aka sani da yawa a baya. A yanayi, magnesium yana kunshe ne a cikin ma'adanai irin su magnesite, dolomite, carnallite, kieserite. Ba zato ba tsammani, da magnesium gishiri samar da ruwa daga bãyan wancan. A babbar adadin da mahadi wannan abu za a iya samu a seawater.
