Qhov sib txawv tseem ceeb ntawm sodium thiab hlau yog tias sodium yog cov hlau mos thiab cov hlau tsis hloov nrog cov ntsiab lus melting tsawg thiab boiling thiab whereas hlau yog ib qho nyuaj hlau thiab cov hlau hloov pauv uas muaj cov ntsiab lus melting thiab kub heev.
Ob leeg sodium thiab hlau yog hlau. Txawm li cas los xij, ob lub hlau no txawv ntawm ib leeg thiab muaj qhov sib txawv ntawm cov khoom siv tshuaj lom neeg thiab lub cev nrog rau qhov tshwm sim.
Sodium yog dab tsi?
Sodium yog cov tshuaj muaj atomic naj npawb 11 thiab cov cim tshuaj Na. Lub cim tshuaj ntawm lub atom no los ntawm nws lub npe Latin Natrium. Sodium tuaj yeem pom nyob rau hauv pawg 1 thiab lub sijhawm 3 ntawm lub sijhawm lub sijhawm ntawm cov ntsiab lus, qhov twg nws tshwm sim raws li s-block element. Peb tuaj yeem categorize sodium li alkali hlau vim nws yog pawg 1 hlau. Kev teeb tsa hluav taws xob ntawm cov tshuaj no yog [Ne]3s1. Ntxiv mus, lub valency ntawm sodium yog 1. Yog li ntawd, ib tug sodium atom yuav tshem tawm ib tug electron thiaj li yuav tau ib tug ruaj khov, noble roj electron configuration.
Txawm li cas los xij, peb tsis tuaj yeem pom cov dawb sodium atoms hauv cov xwm txheej vim tias lawv cov kev ua haujlwm siab. Cov hlau no muaj nyob rau hauv daim ntawv ntawm cov ntsev uas peb tuaj yeem rho tawm cov hlau ntshiab. Tsis tas li ntawd, cov hlau no tuaj yeem raug lees paub tias yog 6th feem ntau cov khoom nyob rau hauv lub ntiaj teb daim tawv nqaij. Sodium feem ntau tshwm sim hauv cov zaub mov xws li feldspar, sodalite, thiab pob zeb ntsev. Yuav luag tag nrho cov ntsev sodium yog dej-soluble. Thaum tawg, cov ntsev no tsim cov sodium cation uas muaj +1 hluav taws xob.
Sodium yog ib qho tseem ceeb rau tsiaj thiab qee cov nroj tsuag. Piv txwv li, sodium cation yog cov cation loj hauv cov kua dej hauv cov tsiaj. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev tsim cov tshuaj sodium chloride, sodium hydroxide, thiab sodium carbonate, uas yog tsim txhua xyoo rau cov kev xav tau sib txawv. Tsis tas li ntawd, metallic sodium yog qhov tseem ceeb hauv kev tsim cov sodium borohydride, sodium azide, indigo, thiab triphenylphosphine. Tsis tas li ntawd, sodium yog siv los ua cov hlau alloying rau cov tshuaj tiv thaiv scaling.
Iron yog dab tsi?
Hlau yog cov khoom siv tshuaj muaj lub cim Fe thiab atomic tooj 26. Nws muaj nyob hauv cov hlau. Hlau yog ntau heev nyob rau hauv lub ntiaj teb, ob qho tib si nyob rau hauv lub sab nrauv thiab sab hauv core. Tsis tas li ntawd, nws muaj lub ntsej muag zoo nkauj zoo nkauj thiab tshwm sim ntawm solid-state nyob rau hauv tus qauv kub thiab siab. Ib yam li ntawd, nws muaj cov ntsiab lus siab melting thiab boiling: 1538 ° C thiab 2862 ° C, feem. Ntxiv mus, qhov ruaj khov thiab feem ntau oxidation xeev ntawm hlau yog +2 thiab +3. Lub xeev +2 yog ferrous, thaum +3 yog ferric. Hlau hlau yog ferromagnetic hlau, thiab nws cov thermal thiab hluav taws xob conductivity kuj siab. Cov qauv siv lead ua ntawm cov hlau tuaj yeem piav qhia raws li lub cev-centered cubic, thiab muaj lwm cov qauv siv lead ua hu ua lub ntsej muag-centered cubic qauv.
Feem ntau, tus neeg laus lub cev muaj nyob ib ncig ntawm 4 grams hlau, feem ntau muaj hemoglobin thiab myoglobin. Cov no yog ob hom proteins uas ua lub luag haujlwm tseem ceeb hauv vertebrate metabolism. Ntxiv mus, hlau yog cov hlau ntawm qhov chaw ua haujlwm ntawm qee cov enzymes redox uas cuam tshuam nrog cellular ua pa thiab oxidation, thiab txo cov nroj tsuag thiab tsiaj.
Qhov txawv ntawm Sodium thiab Hlau yog dab tsi?
Sodium thiab hlau yog cov tshuaj lom neeg hlau uas muaj lub luag haujlwm tseem ceeb hauv tib neeg lub cev. Qhov sib txawv tseem ceeb ntawm sodium thiab hlau yog tias sodium yog cov hlau tsis hloov pauv nrog cov ntsiab lus melting tsawg thiab kub kub thiab yog cov hlau mos, qhov hlau yog cov hlau hloov pauv uas muaj cov ntsiab lus melting siab heev thiab kub kub thiab yog cov hlau tawv.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm sodium thiab hlau.
Summary – Sodium vs Iron
Sodium yog cov tshuaj muaj atomic naj npawb 11 thiab cov cim tshuaj Na. Hlau yog cov khoom siv tshuaj muaj lub cim Fe thiab atomic tooj 26. Qhov sib txawv tseem ceeb ntawm sodium thiab hlau yog tias sodium yog cov hlau tsis hloov pauv nrog cov ntsiab lus qis melting thiab boiling thiab yog cov hlau mos, whereas hlau yog ib qho kev hloov hlau nrog heev. siab melting thiab boiling ntsiab lus thiab yog ib tug tawv hlau.
