valance: Tag nrho cov alkali hlau muaj ib tug electron nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Yuav kom ua tiav qhov kev teeb tsa noble gas, alkali hlau yuav tsum poob ib qho hluav taws xob (valence yog "ib"), hos alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob").
Ib yam li ntawd, koj tuaj yeem nug, qhov txawv ntawm alkali thiab alkaline yog dab tsi?
Ob leeg muaj cov yam ntxwv tseem ceeb. Thaum ntxiv rau dej, ob qho tib si tuaj yeem tsim cov kev daws teeb meem uas muaj pH siab dua (> pH). Lub ntsiab qhov sib txawv ntawm alkali thiab alkaline yog tias alkali hlau muaj ib tug valence electron whereas alkaline ntiaj teb hlau muaj ob valence electrons.
Ib yam li ntawd, qhov sib txawv ntawm cov hlau alkali thiab cov hlau hloov pauv yog dab tsi? Cov kev hloov hlau tsis zoo li cov alkalis yog cov tebchaw. Cov alkalis muaj 1 electron nyob rau hauv lawv lub plhaub sab nraud uas ua rau lawv tsis ruaj khov thiab muaj zog heev. Cov kev hloov hlau Txhua tus muaj 1 lossis 2 electrons nyob rau hauv lawv lub plhaub sab nraud sib nrug ntawm Palladium uas muaj 0 electrons hauv lub plhaub sab nraud.
Tsis tas li ntawd, qhov zoo sib xws thiab qhov sib txawv ntawm alkali hlau thiab alkaline ntiaj teb hlau yog dab tsi?
Cov alkali hlau txhua tus muaj ib tug electron nyob rau hauv lub orbital ntawm lawv lub plhaub sab nrauv; lawv ua ke nrog +1 valence. Cov alkaline ntiaj teb hlau muaj tag nrho s orbital, nrog ob lub electron, yog li lawv muaj ib tug +2 valence.
Lwm lo lus rau alkaline yog dab tsi?
Cov lus ntsig txog alkaline soluble, salty, acrid, alkali, iab, caustic, alkalescent, antacid.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Muaj pes tsawg valence electrons pom nyob rau hauv halogens cov alkali hlau thiab alkaline ntiaj teb hlau?
Cov halogens tag nrho muaj cov txheej txheem hluav taws xob dav dav ns2np5, muab rau lawv xya valence electrons. Lawv yog ib qho hluav taws xob luv luv uas muaj tag nrho sab nrauv s thiab p sublevels, uas ua rau lawv muaj zog heev. Lawv tau txais cov tshuaj tiv thaiv tshwj xeeb nrog cov reactive alkali hlau
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Vim li cas alkali thiab alkaline ntiaj teb hlau yog ntau reactive?
Vim li cas alkaline ntiaj teb hlau tsis tshua muaj zog dua li alkali hlau? A: Nws yuav siv zog ntau dua los tshem tawm ob lub valence electrons los ntawm ib lub atom tshaj li ib lub valence electron. Qhov no ua rau alkaline ntiaj teb hlau nrog lawv ob lub valence electrons tsawg reactive dua alkali hlau nrog lawv ib valence electron
Puas yog alkali hlau thiab alkaline ntiaj teb hlau zoo ib yam?
Valance: Tag nrho cov alkali hlau muaj ib qho hluav taws xob nyob rau hauv lawv lub plhaub sab nraud thiab tag nrho cov alkaline ntiaj teb hlau muaj ob sab electrons. Yuav kom ua tiav cov kev teeb tsa muaj txiaj ntsig zoo, cov hlau alkali yuav tsum poob ib lub tshuab hluav taws xob (valence yog "ib"), thaum alkaline ntiaj teb hlau yuav tsum tshem tawm ob lub electrons (valence yog "ob")
