Nws tuaj yeem muaj ob lub electrons hauv ib qho orbital siab tshaj plaws . Lub s sublevel muaj ib tug xwb orbital , yog li tuaj yeem muaj 2 electrons max . P sublevel muaj 3 orbitals , yog li tuaj yeem muaj 6 electrons max . dsublevel muaj 5 orbitals , yog li tuaj yeem muaj 10 electrons max.
Hais txog qhov no, dab tsi yog qhov ntau tshaj ntawm cov orbitals hauv n 3?
| Orbitals thiab Electron Capacity ntawm FirstFourPrinciple Energy Levels | ||
|---|---|---|
| Principle zog level (n) | Hom sublevel | Muaj pes tsawg tus electrons (2n2) |
| 2 | p | 8 |
| 3 | s | 18 |

Tsis tas li ntawd, qhov siab tshaj plaws ntawm 5d electrons yog dab tsi? Ntau tshaj plaws ntawm cov orbitals hauv qib zog (n2)
| Principal Energy Level (n) | sublevels | tag nrho cov electrons |
|---|---|---|
| 2 | 2s2 pab | 8 |
| 3 | 3s 3d ib | 18 |
| 4 | 4s 4d 4f | 32 |
| 5 | 5s 5d 5f 5g | 50 |
Ntawm no, dab tsi yog qhov ntau tshaj plaws ntawm orbitals nrog N 4?
(a) Thaum = 2, muaj plaub orbitals (ib 2s orbital , thiab peb orbitals labeled2p). Cov plaub no orbitals tau muaj yim electrons. Ib zaug ntxiv, txhua tus orbital tuav ob lub electrons, yog li 50 electrons ua tau fitin lub plhaub. Yog hais tias lub plhaub muaj a siab kawg ntawm 32electrons, qhov tseem ceeb quantum yog dab tsi tus lej , ?
Yuav ua li cas koj txiav txim siab tus naj npawb ntawm orbitals hauv subshell?
Cov tus naj npawb ntawm orbitals nyob rau hauv ib lub plhaub yog lub squareofthe tus thawj xib fwb quantum tus lej : 12 =1, 22 = 4, 32 = 9. Muaj ib orbital hauv ib s subshell (l = 0), peb orbitals v ib p subshell (l = 1), thiab tsib orbitals v ib d subshell (l = 2). Cov tus lej oforbitals hauv a subshell yog li 2(l) +1.

Lub koom haum loj yog dab tsi, los ntawm qhov tsawg tshaj plaws mus rau qhov loj, uas cov kws tshawb fawb feem ntau kawm? 6 theem sib txawv ntawm lub koom haum uas ecologists nquag kawm yog hom, pejxeem, zej zog, ecosystem, thiab biome
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
