Scandium yog ib qho tshuaj lom neeg nrog lub cim Sc thiab atomic tus lej 21. Ib tug silvery-white metallic d-block lub caij, nws muaj keeb kwm tau muab faib ua lub ntiaj teb tsis tshua muaj caij, ua ke nrog yttrium thiab lanthanides.
| Scandium | |
|---|---|
| Oxidation xeev | 0, +1, +2, +3 (ib qho amphoteric oxide) |
| Electronegativity | Pauling nplai: 1.36 |
Ib yam li ib tug yuav nug, vim li cas scandium qhia 3 lub xeev oxidation?
Nws tuaj yeem tsim ib + 3 ion kom ua tiav qhov kev teeb tsa noble gas. Lub zog xav tau kev tshem tawm ib qho hluav taws xob ntxiv los ntawm Sc (+1) yog qhov siab heev, yog li nws nyuaj heev los tsim ib qho +2. oxidation xeev . Yog li ntawd, lub 3 + oxidation xeev yog feem ntau rau Scandium.
Ib yam li ntawd, tus nqi ntawm scandium yog dab tsi? Scandium yog ib qho ntawm ob lub ntsiab lus hauv thawj lub sijhawm hloov hlau uas tsuas muaj ib lub xeev oxidation (zinc yog lwm yam, nrog rau lub xeev oxidation ntawm +2). Tag nrho lwm cov ntsiab lus muaj tsawg kawg yog ob lub xeev oxidation sib txawv.
Ntawm no, dab tsi yog qhov siab tshaj plaws oxidation xeev pom rau scandium?
Scandium ua tiav nws siab tshaj oxidation of +III as ScF3, tsuas paub fluoride ntawm scandium.
Vim li cas scandium tsuas yog tsim 3+ ions?
" Cov ntaub ntawv Scandium qhov ruaj khov heev Ar electron configuration thaum nws poob 3 electrons, yog li ntawd 3 + xeev yog txaus siab heev."

Dab tsi yog oxidation xeev ntawm sulfur hauv so2-3?
Oxidation xeev hauv SO3 (g) yog: Sulfur (+6) & Oxygen (-2), vim SO3 (g) tsis muaj nqi. Txawm li cas los xij hauv (SO3) 2 - (aq) Oxidation xeev yog: Sulfur (+4) & Oxygen (-2). Tsis txhob muab ob qho tsis meej pem, lawv tuaj yeem sau tau yam tsis muaj nqi, tab sis yog tias SO3 yog (aq) nws yuav muaj nqi ntawm -2

Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Lub xeev oxidation ntawm magnesium hauv MgO yog dab tsi?
Hauv kev tsim cov magnesium oxide los ntawm magnesium thiab oxygen, magnesium atoms poob ob lub electrons, los yog oxidation tooj tau nce los ntawm xoom mus rau +2
Lub xeev oxidation ntawm CaCO3 yog dab tsi?
Thaum kawg, tus nqi C yog +4. Cov calcium atom yog anelement pom nyob rau hauv pawg thib ob ntawm lub sij hawm. Cov ntsiab lus no poob ob lub tshuab hluav taws xob hauv cov tshuaj tiv thaiv tshuaj lossis muaj oxidation lub xeev 2+ hauv cov tshuaj lom neeg. Lwm txhais tes thecarbonate yog ib qho ion ntau hauv inorganic chemistry thiab muaj 2-them nqi
