Alpha- tin yog nkig, npub , powdery, semimetallic daim ntawv ntawm tin . Nws yog tsim thaum ntshiab heev tin ua kom txias. Beta- tin yog qhov qub ci iab , mos, conductive, metallic daim ntawv.
Tib neeg kuj nug, puas yog iodine ci los yog npub?
Raws li cov khoom ntshiab, iodine yog ib qho lustrous ntshav-dub nonmetal uas yog khoom raws li tus qauv. Nws sublimes (hloov los ntawm cov khoom mus rau lub xeev gaseous thaum hla ib daim ntawv ua kua) tau yooj yim thiab muab cov pa tsw qab. Txawm hais tias nws yog technically tsis yog hlau, nws nthuav tawm qee qhov zoo ntawm cov hlau.
Qhov thib ob, hom hlau twg yog tin? Tin ( Sn ), cov khoom siv tshuaj muaj nyob rau hauv tsev neeg cov pa roj carbon monoxide, Pawg 14 (IVa) ntawm lub sijhawm teem sijhawm. Nws yog mos, silvery dawb hlau nrog ib tug xiav tinge, paub rau ancients nyob rau hauv tooj liab , alloy nrog tooj liab . Tin yog dav siv rau plating hlau cov kaus poom siv los ua cov ntim khoom noj, hauv cov hlau siv rau cov kabmob, thiab hauv cov khoom siv.
Kuj paub, yog leej faj ci los yog npub?
Cov pa roj carbon, sulfur thiab chlorine yog cov piv txwv ntawm cov khoom tsis yog hlau. Cov hlau tsis muaj hlau muaj cov khoom sib xws. Lawv yog: npub (tsis yog ci iab )
Cov xim ntawm tin yog dab tsi?
Tin yog cov khoom siv tshuaj nrog lub cim Sn (los ntawm Latin: stannum) thiab atomic tooj 50. Tin yog ib qho silvery hlau uas tus yam ntxwv muaj xim daj daj.
Pom zoo:
Puas yog tin yog kua roj lossis khoom?
Tus lej Atomic ntawm cov khoom no yog 50 thiab cov cim tshuaj yog Sn. Cov ntsiab lus tuaj yeem raug cais raws li lawv lub cev lub xeev (States of Matter) e.g. gas, khoom los yog kua. Cov khoom no yog ib qho khoom. Tin yog cais nyob rau hauv 'Lwm Hlau' seem uas tuaj yeem nyob hauv pawg 13, 14, thiab 15 ntawm Lub Sij Hawm Lub Sij Hawm
Puas yog npib tsib xee ci los yog npub?
Nickel yog ib qho nyuaj, malleable, ductile hlau. Nws yog ci iab nyiaj hlau nrog me ntsis kub tinge uas yuav siv sij hawm ahigh polish thiab resists corrosion. Lub caij ua oxidize, tab sis txheej oxide tiv thaiv kev ua haujlwm ntxiv ntawm kev ua haujlwm Nws yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov

Yuav ua li cas muaj pes tsawg electrons puas ib tug uncharged atom ntawm tin muaj?
Cov tin atom no muaj 50 protons, 69 neutrons thiab 48 electrons
Puas yog atoms ua los ntawm cov ntsiab lus los yog cov khoom tsim tawm ntawm atoms?
Atoms yeej ib txwm ua los ntawm cov khoom. Atoms qee zaum ua los ntawm cov khoom. Lawv txhua tus muaj ob tsab ntawv hauv lawv cov cim atomic. Cov muaj pes tsawg leeg
