Cov haujlwm series yog a daim ntawv teev cov khoom nce kev txiav txim ntawm lawv reactivity . Txij li thaum hlau hloov lwm cov hlau, thaum nonmetals hloov lwm yam nonmetals , lawv txhua tus muaj ib cais kev ua si . 2is ib kev ua yeeb yam series ntawm tus halogens.

Hauv qhov no, dab tsi yog qhov reactivity series ntawm cov hlau tsis yog?

Tsis yog - hlau hauv reactivityseries Nws yog qhov tsim nyog los tso cov pa roj carbon thiab hydrogen rau hauv cov khoom reactivity series vim hais tias cov ntsiab lus no tuaj yeem siv los rho tawm hlau . Ntawm no yog qhov reactivity series suav nrog carbon thiab hydrogen: Nco ntsoov tias zinc thiab hlau tuaj yeem hloov chaw los ntawm lawv cov oxides siv carbon tab sis tsis yog siv hydrogen.

Ib sab saum toj, dab tsi yog qhov kev ua yeeb yam thiab nws ua haujlwm li cas? Cov kev ua haujlwm ntawm cov hlau yog ib qho cuab yeej siv los kwv yees cov khoom hauv hloov chaw Cov tshuaj tiv thaiv thiab reactivity ntawm cov hlau nrog dej thiab acids hauv kev hloov cov tshuaj tiv thaiv thiab oreextraction. Nws tuaj yeem siv los kwv yees cov khoom lag luam zoo sib xws nrog cov hlau sib txawv.

Ua kom pom qhov no, dab tsi yog qhov kev ua haujlwm ntawm cov ntsiab lus?

Cov reactivity series yog a series ofmetals, nyob rau hauv kev txiav txim ntawm reactivity los ntawm siab tshaj mus rau qis tshaj. Nws yog siv los txiav txim siab cov khoom ntawm ib qho kev hloov pauv, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv series.

Vim li cas K thiaj li muaj zog dua Li?

Li no poov tshuaj yog ntau reactive tshaj sodium. Yog li poov tshuaj yog ntau reactive tshaj lithium vim lub sab electron ntawm a poov tshuaj atom yog ntxiv los ntawm nws cov nucleus tshaj sab nraud electron ntawm a lithium atom. Francium atoms, nrog 7 lub plhaub, yog cov atoms loj tshaj plaws hauv Group1.
