Cov kev ua yeeb yam series yog lis hlau thiab lawv ib nrab-reactions teem nyob rau hauv xaj txo qhov yooj yim ntawm oxidation los yog ua kom muaj peev xwm coj ib qho hluav taws xob.

Hais txog qhov no, kev ua haujlwm ntawm cov hlau txiav txim siab li cas?

Cov kev ua yeeb yam series yog ib daim duab ntawm hlau teev nyob rau hauv kev txiav txim ntawm tus txheeb ze poob reactivity . Qhov no qhia tau hais tias magnesium yog ntau reactive tshaj zinc thiab ob qho tib si hlau muaj ntau reactive tshaj hydrogen. Qhov kev hloov pauv thib peb no tuaj yeem siv rau ib qho twg hlau uas tshwm qis dua nws tus kheej ntawm lub rooj.

Ib yam li ntawd, cov kev ua ub no raug teeb tsa li cas? Ib kev ua yeeb yam series , raws li tau hais dhau los, yog ib daim ntawv teev npe lossis cov lus hais koom los ntawm yooj yim npaum li cas lawv undergo ib tug tshuaj tiv thaiv. Rau cov hlau, qhov loj dua kev ua si , qhov yooj yim dua lawv poob electrons, tsim cov ions zoo. Nrog nonmetals, qhov ntau dua kev ua si , qhov yooj yim lawv tau txais electrons, tsim tsis zoo ions.

Kuj paub, qhov kev ua yeeb yam txhais li cas?

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.

Qhov twg hlau yog reactive tshaj plaws?

cesium
