FIGURE 5.9 Tus xub qhia ib txoj hauv kev thib ob ntawm kev nco qab qhov kev txiav txim uas cov qib sub sau. Table 5.2 qhia cov electron configurations ntawm cov ntsiab lus nrog atomic tooj 1 txog 18.
| Element | Atomic naj npawb | Electron configuration |
|---|---|---|
| sulfur | 16 | 1s ib 2 2s ib 2 2 ib p63s ib 2 3 ua p4 |
| tshuaj chlorine | 17 | 1s ib 2 2s ib 2 2 ib p63s ib 2 3 ua p 5 |
| argon | 18 | 1s ib 2 2s ib 2 2 ib p63s ib 2 3 ua p6 |
Ua raws li qhov no, qhov kev teeb tsa hluav taws xob rau BE 2 yog dab tsi?
Txij li 1s tuaj yeem tuav tau ob electrons qhov seem 2 electrons vim mus nyob rau 2 lub orbital. Yog li ntawd lub Be electron configuration yuav 1s 2 2s ib 2 . Cov kev teeb tsa notation muab txoj hauv kev yooj yim rau cov kws tshawb fawb los sau thiab sib txuas lus li cas electrons yog teem ib ncig ntawm lub nucleus ntawm ib atom.
Tsis tas li ntawd, lub ntsiab lus twg muaj qhov teeb tsa hluav taws xob ntawm 2/8 1? Daim ntawv teev cov khoom nrog electrons ib lub plhaub
| Z | Element | No. ntawm electrons/plhaub |
|---|---|---|
| 18 | Argon | 2, 8, 8 |
| 19 | Potassium | 2, 8, 8, 1 |
| 20 | Calcium | 2, 8, 8, 2 |
| 21 | Scandium | 2, 8, 9, 2 |
Nyob rau hauv no txoj kev, dab tsi lub caij muaj ib tug electron configuration ntawm 2 4?
Cov npe ntawm Electron Configurations of Elements 7
| NUMBER | TSEEM CEEB | ELECTRON CONFIGURATION |
|---|---|---|
| 1 | Hydrogen | 1s ib1 |
| 2 | Helium | 1s ib2 |
| 3 | Lithium | [Nws] 2s1 |
| 4 | Beryllium | [Nws] 2s2 |
Dab tsi yog qhov kev teeb tsa hluav taws xob ntawm thawj 20 lub ntsiab lus?
Cov lus hauv qab no qhia txog lub xeev hauv av electron configuration ntawm thawj 20 ntsiab lus nyob rau ntawm lub rooj sib tham. NB: tus superscripts ntxiv mus rau tus lej atomic ntawm lub atom.
