Hauv chemistry, a reactivity series (los yog kev ua yeeb yam series ) yog ib qho empirical, xam, thiab structurally analytical progression ntawm a series ntawm cov hlau, npaj los ntawm lawv " reactivity "los ntawm siab tshaj mus rau qis tshaj.
Ib yam li ntawd, koj tuaj yeem nug, vim li cas cov npe ntawm cov hlau hu ua Kev Ua Haujlwm Series?
Kev Ua Haujlwm Series Txhais: The kev ua yeeb yam series ntawm hlau yog ib daim ntawv teev cov hlau ranked nyob rau hauv kev txiav txim ntawm txo reactivity tshem tawm cov roj hydrogen los ntawm cov dej thiab cov kua qaub. Nws kuj tseem siv tau los twv seb qhov twg hlau yuav tshem lwm yam hlau hauv cov kev daws teeb meem aqueous.
Tsis tas li ntawd, yog lithium reactive ntau dua li magnesium? Lithium yog lub lightest khoom thiab hlau thiab lub thib peb lightest keeb. Tom ntej no, sodium - ntau reactive tshaj lithium . Tom ntej no, Magnesium yog qee yam reactive.
Ib yam li ntawd, vim li cas cov kev ua yeeb yam ua haujlwm?
Cov kev ua yeeb yam series ntawm cov hlau yog ib qho cuab yeej empirical siv los kwv yees cov khoom hauv kev hloov pauv thiab reactivity ntawm cov hlau nrog dej thiab acids hauv kev hloov cov tshuaj tiv thaiv thiab ore extraction. Nws ua tau siv los kwv yees cov khoom lag luam zoo sib xws nrog cov hlau sib txawv.
Dab tsi yog kev ua yeeb yam series Nws pab peb li cas hauv kev kwv yees?
Nws yog series txo qhov kev txiav txim ntawm cov hlau ' reactivity . Hydrogen yog qhov chaw nyob nruab nrab ntawm series . Sab saum toj hydrogen hlau yog ntau reactive nyob rau hauv cov xwm hauv qab no yog tsawg. Hlau uas yog ntau reactive nws displaces ib tug tsawg reactive hlau los ntawm nws cov ntsev tov.

Lawv kuj tau piav qhia los ntawm biotic yam zoo li cov nroj tsuag thiab tsiaj lub neej. Ib thaj tsam sib txawv tshwm sim thaum ob daim phiaj tectonic txav deb ntawm ib leeg
Yuav ua li cas koj thiaj nrhiav tau tus nqi ntawm tus qauv txhais tau tias?
Qhov xav tau tus nqi ntawm tus qauv txhais tau tias yog cov pej xeem txhais tau tias, thiab SE ntawm tus qauv txhais tau tias yog SD ntawm cov pej xeem, muab faib los ntawm lub hauv paus square ntawm tus qauv loj
Lub hauv paus ntsiab lus Aufbau ua haujlwm li cas uas txhais tau hais tias orbitals tau sau los ntawm hauv qab los yog saum toj saud nyob ntawm daim duab)?
Los ntawm Hauv qab Up: Cov chav yuav tsum tau sau los ntawm hauv av pem teb mus rau. Hauv pem teb siab dua qhov kev txiav txim yuav hloov me ntsis. Aufbau Txoj Cai: cov electrons sau cov orbitals ntawm lub zog qis tshaj mus rau lub zog siab tshaj. Nyob rau hauv lub xeev av tag nrho cov electrons nyob rau hauv qis tshaj tau lub zog theem
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
