List of Cations
| Index | Lub npe | Cim |
|---|---|---|
| 81 | tin (IV) | Sn 4 + |
| 82 | coj (II) | Pb2+ |
| 83 | lead (IV) | Pb 4 + |
| 84 | ammonium | NH 4 + |
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ionic nqi ntawm tin?
Lub cim " Sn " sib raug rau lub ntsiab tin , uas tej zaum yuav muaj ib qho +2 lossis +4 nqi hauv ionic cov tebchaw (rau ib daim ntawv teev cov oxidation xeev muaj rau cov ntsiab lus, sab laj ib lub sij hawm los yog saib ntawm no). Tin yog hlau nyob rau hauv no compound thiab ua hauj lwm raws li nws cation; Yog li ntawd, peb pib lub npe tawm nrog " tin ."
Tsis tas li ntawd, qhov twg Monatomic ion muaj tus nqi +2? Hauv lwm lo lus, calcium ion, Ca2+ yog ib txwm +2. Tsis txhob hu CaCl2 “ calcium (II) chloride. Nws lub npe yog " calcium chloride."
Hauv qhov no, lub npe ntawm ion sn2+ yog dab tsi?
Tin, ion (Sn2+) Nqe lus piav qhia: Tin(2+) yog ib qho kev qhia txog monoatomic thiab divalent hlau cation.
Muaj pes tsawg ions ua tin tsim?
Vim li cas cov hlau lead thiab tin form + 2 ion ua es tsis yog +4 zoo li hauv lwm cov ntsiab lus hauv pawg carbon?

Dab tsi yog tus nqi ntawm lub atom uas tau txais electrons?
Ib qho ion yog ib qho atom uas tau txais lossis poob ib lossis ntau dua electrons thiab yog li ntawd muaj qhov tsis zoo lossis qhov zoo. Ib qho cation yog ib qho atom uas tau poob ib qho hluav taws xob valence thiab yog li ntawd muaj ntau qhov zoo protons dua li cov hluav taws xob tsis zoo, yog li nws raug nqi zoo
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
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
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
