Protactinium (yav tas los protoactinium) yog cov khoom siv tshuaj nrog lub cim Pa thiab tus lej atomic 91. Nws yog tuab, silvery-grey actinide hlauuas nkag tau nrog oxygen, dej. vapor thiab inorganic acids.
YPuas yog protactinium tsis yog hlau?
Density (ze r.t.) ~ 9.9 µm / (m⋅K) (ntawm r.t.) Protactinium (yav tas los protoactinium) yog cov khoom siv tshuaj nrog lub cim Pa thiab tus lej atomic 91. Nws yog ntom, silvery-grey actinide hlau uas nkag tau yooj yim nrog oxygen, dej vapor thiab inorganic acids.
hom hlau twg yog protactinium?
Protactinium Properties
Protactinium yog radioactive actinide pawg hlau nrog lub cim atomic Pa, atomic tooj 91, thiab atomic hnyav 231. Nws lwj los ntawm alpha-emission.. Nws yog Block F, Pab Pawg 3, Lub Sijhawm 7.
Puas yog actinium yog hlau lossis nonmetal?
Tshuaj, actinium, uas nyob rau hauv nws haiv neeg daim ntawv yog ib tug silvery hlau, muaj cov yam ntxwv zoo ib yam li lwm yam tsawg lub ntiaj teb xws li lanthanum. Actinium muaj peb caug-rau-siv isotopes tag nrho cov uas yog radioactive.
Kev faib tawm ntawm protactinium yog dab tsi?
Protactinium yog ib yam tshuaj muaj cim Pa thiab atomic tooj 91. Classified as an actinide, Protactinium yog ib qho khoom ntawm chav tsev kub.

Puas yog boron yog hlau nonmetal lossis metalloid?
Boron yog ib yam tsis yog xim hlau thiab tsuas yog tsis yog hlau ntawm pab pawg 13 ntawm lub sijhawm cov ntsiab lus. Boron yog tsis muaj electron, muaj qhov tsis muaj p-orbital. Nws muaj ntau hom, feem ntau yog amorphous boron, hmoov tsaus, tsis muaj zog rau oxygen, dej, acids thiab alkalis .
Cov hlau nplaum puas lo rau txhuas lossis hlau?
Metals uas tsis nyiam Magnets Hauv lawv lub xeev ntuj, cov hlau xws li txhuas, tooj dag, tooj liab, kub, txhuas thiab nyiaj tsis nyiam cov hlau nplaum vim tias lawv yog cov hlau tsis muaj zog. Txawm li cas los xij, koj tuaj yeem ntxiv cov khoom xws li hlau lossis hlau rau cov hlau tsis muaj zog kom ua rau lawv muaj zog .
Puas yog arsenic yog hlau lossis nonmetal?
1.2. Arsenic (atomic tooj, 33; txheeb ze atomic mass, 74.92) muaj tshuaj lom neeg thiab lub cev muaj zog nruab nrab ntawm ib tug hlau thiab a non-metal, thiab feem ntau hu ua metalloid lossis semi-hlau.. Nws belongs rau Pawg VA ntawm Lub Sij Hawm Lub Sij Hawm, thiab tuaj yeem muaj nyob hauv plaub lub xeev oxidation:
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
Dab tsi yog hlau lossis hlau?
Steel muaj zog dua hlau (yield thiab qhov kawg tensile zog) thiab tawv dua ntau hom hlau ib yam nkaus (feem ntau ntsuas raws li tawg toughness). Cov hom hlau feem ntau muaj qhov sib ntxiv ntawm tsawg dua. 5% carbon los ntawm qhov hnyav. … Lwm cov ntsiab lus uas feem ntau pom hauv cov hlau yog manganese, silicon, phosphorus, thiab sulfur .
