Table of Flame Test Colors
| Xim Xim | Hlau Ion |
|---|---|
| Ci daj | Sodium |
| Kub los yog xim av daj | Hlau (II) |
| Txiv kab ntxwv | Scandium, hlau (III) |
| Txiv kab ntxwv mus rau txiv kab ntxwv-liab | Calcium |
Ib yam li ntawd, xim dab tsi hlau hlawv?
Sodium, Hlau : Daj Yog tias koj tus qauv muaj cov kab mob sodium, lub xim koj pom tej zaum yuav muaj xws li kev npaj txhij txog kev pab los ntawm daj. Hlau kuj tuaj yeem tsim cov nplaim kub (txawm tias qee zaum txiv kab ntxwv).
Ib tug kuj yuav nug, yog vim li cas hlau ions tsim Xim nplaim taws? Thaum koj ua kom sov lub atom, qee qhov ntawm nws cov electrons yog zoo siab * rau siab zog ntau dua. Thaum ib qho hluav taws xob poob los ntawm ib theem mus rau qib qis zog, nws tawm lub zog quantum. Qhov sib txawv ntawm lub zog sib txawv rau txhua lub atom. tsim tawm txawv xim . Txhua hlau muab tus yam ntxwv nplaim taws emission spectrum.
Yog li ntawd, puas tag nrho cov hlau ions tsim cov nplaim xim?
Tsis yog tag nrho cov hlau ions muab nplaim xim . Rau pawg 1 compounds, nplaim taws kev ntsuam xyuas feem ntau yog qhov yooj yim tshaj plaws ntawm kev txheeb xyuas qhov twg hlau koj tau txais. Rau lwm tus hlau , feem ntau muaj lwm txoj hauv kev yooj yim uas txhim khu kev qha - tab sis cov nplaim taws xeem tuaj yeem muab cov lus qhia tseem ceeb raws li qhov yuav saib.
Cov xim dab tsi hlawv?
Vim hais tias txhua lub ntsiab lus muaj ib qho kev qhia raws nraim kab emission spectrum, cov kws tshawb fawb muaj peev xwm txheeb xyuas lawv los ntawm cov xim ntawm cov nplaim taws lawv tsim. Piv txwv li, tooj liab tsim cov nplaim xiav, lithium thiab strontium ib nplaim liab, calcium thiab txiv kab ntxwv nplaim taws, sodium hluav taws daj, thiab barium nplaim taws ntsuab.
Pom zoo:
Cov nplaim xim ntawm strontium yog dab tsi?
Flame Tests Element xim Rubidium liab (liab-violet) Cesium xiav/violet (saib hauv qab) Calcium txiv kab ntxwv-liab Strontium liab
Cov xim hlau yog dab tsi?
Hlau yog ib qho kev hloov pauv hlau. Xim: silvery-grey. Atomic nyhav: 55.847
Vim li cas nws nyuaj rau txheeb xyuas cov hlau ions los ntawm Xim ntawm nplaim taws?
Lub zog no raug tso tawm raws li lub teeb, nrog cov yam ntxwv nplaim xim ntawm cov hlau ions sib txawv vim qhov sib txawv ntawm cov hluav taws xob hloov pauv. Raws li tau hais, cov kev sim no ua haujlwm zoo dua rau qee cov hlau ions dua li lwm yam; tshwj xeeb, cov ions pom nyob rau hauv kab hauv qab ntawm cov infographic feem ntau yog faus thiab nyuaj rau qhov txawv
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
