Chlorine belongs rau tus pab pawg ntawm halogens- ntsev-forming cov ntsiab lus - ua ke nrog fluorine (F), bromine (Br), iodine (I) thiab astatine (At). Lawv tag nrho nyob rau hauv kab thib ob los ntawm sab xis ntawm lub daim ntawv qhia hnub hauv Pab pawg 17. Lawv cov khoom siv hluav taws xob zoo sib xws, muaj xya lub tshuab hluav taws xob hauv lawv lub plhaub sab nraud.
Hais txog qhov no, pab pawg twg yog chlorine?
Chlorine yog nyob rau hauv pab pawg 17 ntawm lub sij hawm lub sij hawm, kuj hu ua halogens, thiab tsis pom raws li lub caij nyob rau hauv cov xwm - tsuas yog raws li ib tug compound. Feem ntau ntawm cov no yog ntsev, orsodium chloride, thiab cov poov tshuaj sib txuas sylvite (los yog potassiumchloride) thiab carnallite (potassium magnesium chloridehexahydrate).
chlorine nyob qhov twg? Chlorine tuaj yeem yog pom nyob rau hauv abundance nyob rau hauv ob lub ntiaj teb crust thiab nyob rau hauv dej hiav txwv dej. Hauv dej hiav txwv, tshuaj chlorine yog pom raws li ib feem ntawm cov compound sodium chloride (NaCl), los yog lub rooj ntsev. Nyob rau hauv lub ntiaj teb lub crust, feem ntau cov minerals muaj tshuaj chlorine suav nrog halite (NaCl), carnallite, thiab sylvite (KCl).
Tsuas yog li ntawd, pab pawg twg ntawm cov ntawv teev sijhawm lithium belongs rau?
Cov alkalimetals yog rau chemical cov ntsiab lus hauv Pab pawg 1, sab laug ntawm sab hauv daim ntawv qhia hnub . Lawv yog lithium (Li), sodium (Na), poov tshuaj (K), rubidium (Rb), cesium (Cs), thiab francium (Fr).
Cov tshuaj fluorine thiab chlorine yog pab pawg twg?
Cov halogens nyob rau sab laug ntawm lub noble gaseson lub sij hawm lub rooj. Cov tsib tshuaj lom, tsis yog xim hlau pleev xim Pab pawg 17 ntawm lub sij hawm lub sij hawm thiab muaj xws li: tshuaj fluorine (F), tshuaj chlorine (Cl), bromine (Br), iodine (I), thiab astatine (At).

Dab tsi yog lub ntsiab lus ntawm ib pab pawg ntawm cov lus teev sijhawm?
Nyob rau hauv chemistry, ib pab pawg (tseem hu ua tsev neeg) yog ib kem ntawm cov ntsiab lus nyob rau hauv lub sij hawm lub sij hawm ntawm cov tshuaj. Muaj 18 pawg lej nyob rau hauv daim ntawv teev sijhawm; cov kab f-block (nruab nrab ntawm pawg 3 thiab 4) tsis suav nrog
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi yog pawg ntawm cov lus teev sijhawm?
Muaj ntau txoj hauv kev los faib cov ntsiab lus, tab sis lawv feem ntau muab faib ua hlau, semimetals (metalloids), thiab nonmetals. Koj yuav pom ntau pab pawg tshwj xeeb, xws li cov hlau hloov pauv, cov av tsis tshua muaj, cov hlau alkali, alkaline ntiaj teb, halogens, thiab cov roj av zoo
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
