Qhov sib txawv tseem ceeb ntawm halogen thiab hlau halide yog tias halogen yog ib pawg 17 tshuaj lom neeg, whereas hlau halide yog ib qho chaw uas muaj hlau thiab halogen.
Hlau halides yog ionic lossis covalent compounds ntawm halogens. Ib qho halogen yog ib qho tshuaj lom neeg thiab tag nrho cov ntsiab lus hauv pawg 17 ntawm lub sij hawm lub sij hawm hu ua halogens feem ntau.
Halogen yog dab tsi?
Halogens yog pab pawg 17 cov tshuaj lom neeg hauv lub sijhawm. Cov pab pawg muaj tsib yam tshuaj, suav nrog Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), thiab Astatine (At). Feem ntau peb siv lub cim X los ua lub cim halogen. Lo lus halogen hais txog "tsim ntsev". Qhov ntawd txhais tau tias; Cov ntsiab lus tshuaj no zoo li tsim cov ntsev thaum reacting nrog hlau. Ib qho tshuaj tiv thaiv ntawm halogen thiab hlau ua rau ntau hom ntsev sib txuas. Cov pab pawg halogen muaj cov ntsiab lus uas muaj nyob hauv ntau theem ntawm cov teeb meem. Piv txwv li, fluorine thiab chlorine yog gases, thaum bromine yog kua thiab iodine yog ib qho khoom ntawm chav tsev kub.

Down pawg ntawm halogens nyob rau hauv lub sij hawm lub sij hawm, reactivity txo, qhov luaj li cas ntawm ib tug atom nce, electronegativity txo, theem ntawm cov teeb meem hloov los ntawm ib tug roj rau cov khoom, thiab lwm yam. Thaum xav txog kev siv cov halogens, lawv yog. muaj txiaj ntsig zoo li tshuaj tua kab mob, tseem ceeb rau cov teeb halogen, muaj txiaj ntsig zoo li cov khoom xyaw hauv qee cov tshuaj, thiab lwm yam.
Hlau Halide yog dab tsi?
Hlau halides yog ionic lossis covalent compounds ntawm cov hlau thiab halogens. Ib co covalent hlau halide compounds tshwm sim raws li ib tug discrete molecules los yog raws li polymeric lug. Tag nrho cov halogens nyiam hnov mob nrog hlau, ua hlau halides.

Txoj kev xav, peb tuaj yeem tsim cov hlau halide ntawm cov tshuaj tiv thaiv ntawm cov tshuaj, tab sis hom tshuaj tiv thaiv no yog exothermic heev. Yog li ntawd, peb tuaj yeem siv lwm txoj hauv kev xws li neutralization cov tshuaj tiv thaiv ntawm cov hlau oxides thiab hydroxides.
Thaum xav txog cov khoom, ionic hlau halides ruaj khov heev; Yog li, lawv zoo li muaj cov ntsiab lus melting thiab boiling siab. Txawm li cas los xij, cov tshuaj no tau yaj hauv dej. Qee qhov sib xyaw ua ke yog deliquescent thiab. Txawm li cas los xij, lawv tsis zoo soluble hauv cov kuab tshuaj organic. Ntxiv mus, discrete hlau halide molecules muaj qhov sib piv qis melting thiab boiling ntsiab lus.
Qhov txawv ntawm Halogen thiab Hlau Halide yog dab tsi?
Qhov sib txawv tseem ceeb ntawm halogen thiab hlau halide yog tias halogen yog Pawg 17 tshuaj lom neeg, thaum hlau halide yog cov khoom sib xyaw uas muaj hlau thiab halogen. Hauv lwm lo lus, halogen yog cov khoom siv tshuaj thaum hlau halide yog cov tshuaj lom neeg.
Ntxiv mus, qhov sib txawv ntxiv ntawm halogen thiab hlau halide yog tias halogen tuaj yeem muaj nyob hauv ntau theem ntawm cov teeb meem, suav nrog fluorine thiab chlorine hauv cov pa roj, bromine hauv cov kua theem, thiab iodine hauv cov khoom theem, tab sis hlau halides muaj nyob rau hauv cov khoom theem.
Summary – Halogen vs Hlau Halide
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm halogen thiab hlau halide yog tias halogen yog Pawg 17 tshuaj lom neeg, qhov hlau halide yog cov khoom sib xyaw uas muaj hlau thiab halogen. Yeej, halogen yog cov khoom siv tshuaj thaum hlau halide yog cov tshuaj lom neeg.
