Cov chemical zog ntawm ib lub caij yog txiav txim siab los ntawm tus naj npawb ntawm valence electrons. Daim duab electron dot yog ib qho qauv ntawm ib qho atom nyob rau hauv uas txhua lub dot sawv cev rau valence electron.
Ib yam li ntawd, nws raug nug, dab tsi txiav txim siab cov khoom siv tshuaj lom neeg ntawm atom?
Cov chemical zog ntawm ib lub caij yog txiav txim siab los ntawm configuration ntawm nws cov electrons nyob rau hauv orbit ncig nws nucleus. Tus naj npawb ntawm cov electrons nyob rau hauv lub orbit yog sib npaug rau tus naj npawb ntawm protons nyob rau hauv lub nucleus (txhua tus proton muaj ib tug hluav taws xob nqi ntawm ib tug ntxiv, thaum txhua tus electron muaj tib nqi xwb tsis zoo ib tug).
Tom qab ntawd, lo lus nug yog, dab tsi txiav txim siab txog kev coj tus cwj pwm ntawm cov ntsiab lus quizlet? Cov chemical cwj pwm ntawm ib qho atom yog txiav txim siab los ntawm kev faib cov hluav taws xob hauv cov hluav taws xob hluav taws xob.
Qhov thib ob, dab tsi subatomic particle txiav txim siab cov tshuaj lom neeg ntawm atom?
hluav taws xob
Vim li cas electrons txiav txim siab li cas atom yuav hnov mob chemical?
Tus naj npawb ntawm electrons hauv ib atom yog txiav txim siab los ntawm tus naj npawb ntawm protons. Qhov no txhais tau tias feem ntau atoms muaj ib feem ntawm sab nraud lub zog. Thaum twg atoms teb , lawv zoo li sim thiab ua tiav qib siab sab nraud, los ntawm kev poob sab nraud electrons , los ntawm kev nce ntxiv electrons los yog los ntawm kev sib koom electrons nrog lwm tus atom.

Dab tsi yog tsib yam pov thawj uas koj tuaj yeem siv los txiav txim seb puas muaj tshuaj lom neeg tshwm sim?
Qee cov cim qhia txog kev hloov tshuaj lom neeg yog kev hloov xim thiab tsim cov npuas. Lub tsib yam kev hloov ntawm tshuaj lom neeg: xim chage, tsim ntawm precipitate, tsim cov roj, tsw hloov, kub hloov
Cov khoom siv tshuaj lom neeg nyob ntawm dab tsi?
Cov khoom siv tshuaj lom neeg ntawm cov ntsiab lus nyob ntawm ib qho khoom siv hluav taws xob teeb tsa. Thaum lub zog siab tshaj plaws ntawm lub atom tau ntim nrog cov hluav taws xob, lub atom ruaj khov thiab tsis zoo li yuav tshwm sim. Cov khoom siv tshuaj lom neeg ntawm cov khoom nyob ntawm seb muaj pes tsawg tus valence electrons
Cov khoom siv tshuaj lom neeg ntawm cov zaub mov yog dab tsi?
Cov khoom uas pab geologists txheeb xyuas cov pob zeb hauv pob zeb yog: xim, hardness, luster, crystal forms, ntom, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab feem ntau los ntawm cov qauv siv lead ua ntawm qib atomic. Xim thiab ntom yog txiav txim siab feem ntau los ntawm cov tshuaj muaj pes tsawg leeg
Dab tsi tuaj yeem siv los txiav txim siab tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
