Ib ob peb lub ntsiab lus, tag nrho cov hlau, tuaj yeem tsim ntau dua li tus nqi them. Piv txwv li, hlau atoms tuaj yeem tsim 2+ cations lossis 3+ cations.
Can Cr tsim cov cations nrog ntau tus nqi?
A Vim tias chromium yog cov hlau hloov pauv, nws tuaj yeem tsim cov cations nrog cov nqi sib txawv Tus lej Roman qhia peb tias tus nqi zoo hauv qhov no yog +3, yog li cov cation yog Cr 3+ B Oxide is O 2- Yog li ob cations (Cr 3+) thiab peb anions (O 2−) yuav tsum muab cov hluav taws xob tsis zoo, Cr 2 O 3
Yuav ua li cas yog cov hlau uas feem ntau yuav tsim cations nrog cov nqi sib txawv?
Cov khoom hlau uas feem ntau yuav tsim cov cations nrog cov nqi sib txawv yog cov hlau hloov pauv.
Puas AG daim ntawv muaj ntau yam cations?
Txawm hais tias nyiaj tuaj yeem tsim tau ob qho tib si +1 thiab +2 cations, qhov +2 tsis tshua muaj heev uas peb feem ntau hu ua Ag+ ua nyiaj ion, tsis yog nyiaj (I) ion. Ag2+ is called silver(II) ion. Peb yuav xav tias tag nrho cov hlau hlau lwm yamdua li cov tau hais los saum toj no tuaj yeem muaj ntau dua ib tus nqi, yog li lawv cov npe cation yuav suav nrog tus lej Roman.
Cov cations twg muaj ntau tus nqi?
Ib ob peb lub ntsiab lus, tag nrho cov hlau , tuaj yeem tsim ntau dua ib qho nqi them. Piv txwv li, hlau atoms tuaj yeem tsim 2+ cations lossis 3+ cations. Cob alt yog lwm lub ntsiab lus uas tuaj yeem tsim ntau tshaj li ib qho kev them nyiaj ion (2+ thiab 3+), thaum cov hlau lead tuaj yeem tsim 2+ lossis 4+ cations. … Yog li Na + yog sodium ion; Ca 2+ yog calcium ion.
