Sau cov txheej txheem hluav taws xob sab nraud ntawm s-, p-, d- thiab f-block ntsiab.
| Element | General sab nrauv electronic configuration |
|---|---|
| p- thaiv (hlau & tsis yog hlau) | ns2np1–6n = 2 – 6 |
| d- thaiv ( Hloov cov ntsiab lus ) | (n–1) d1–10 ns0–2n = 4 – 7 |
| f – thaiv (hauv Hloov cov ntsiab lus ) | (n-2) f 1–14(n-1) d0–10ns2n = 6 – 7 |
Yog li ntawd, dab tsi yog qhov kev teeb tsa hluav taws xob dav dav ntawm F thaiv cov ntsiab lus?
Cov General hluav taws xob configuration f - thaiv cov ntsiab lus yog:: (n-2) f ^1–14(n-1)d^0–1ns^2. Theblock cov ntsiab lus yog Lanthanides thiab Actinides, tseem hu ua kev hloov pauv sab hauv cov ntsiab lus . Lawv muab tso rau nyias hauv qab no rau hauv qab lub sij hawm lub sij hawm raws li ib tug 'Island ntawm cov ntsiab lus '.
Ib sab saum toj no, lub teeb tsa hluav taws xob ntawm S Block yog dab tsi? s - Thaiv Cov ntsiab lus sab nraud electronic configuration yog n s 1 ns^1 n s 1i ib n s 2 ns^2 n s 2. Pawg 1 (Alkali Metals) thiab Pawg 2 (Alkali Earth Metal) belongs rau s - thaiv cov ntsiab lus. Daim duab muab qhia pom cov khoom muaj nyob hauv s - thaiv ntawm daim ntawv periodic.
Yuav ua li cas koj sau ib tug general electronic configuration?
Cov kauj ruam
- Nrhiav koj tus lej atomic.
- Txiav txim siab tus nqi ntawm lub atom.
- Nco cov npe ntawm cov orbitals.
- Nkag siab txog kev teeb tsa hluav taws xob.
- Nco qhov kev txiav txim ntawm lub orbitals.
- Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom.
- Siv lub sij hawm ntev raws li qhov pom kev luv luv.
F yog dab tsi hauv electron configuration?
