M plhaub tsuas tuav yim electrons. M plhaub tuaj yeem tuav txog li 18 electrons thaum koj txav mus rau ntau dua atomic tooj. Cov ntau tshaj ntawm electrons koj yuav pom nyob rau hauv ib lub plhaub yog 32.
Cov lus nug tseem yog, dab tsi subshells thiab orbitals muaj nyob hauv M plhaub?
thib ob (L) plhaub muaj ob subshells npe,2s2p. peb ( M ) plhaub muaj 3s, 3p, 3d. plaub (N) plhaub muaj 4s, 4p, 4d 4f. thib tsib (O) plhaub muaj 5s, 5p, 5d,5f.
Muaj pes tsawg lub orbitals nyob hauv 5th Plhaub? Rau 5th kob ,nqe 5. Rau n=5, tso cai rau l yog 0, 1, 2, 3 thiab 4 (l-1). 1+3+5+7+9 = 25 orbitals . Koj tuaj yeem siv qhov sib npaug hauv qab no: tus lej ntawm orbitals = n².
Ib yam li ntawd, nws tau nug, muaj pes tsawg Subshells muaj nyob hauv M plhaub?

| Plhaub | Subshell | Tag Nrho Cov Hluav Taws Xob hauv Plhaub |
|---|---|---|
| 1st Plhaub | 1s ib | 2 |
| 2nd Plhaub | 2 s, 2 ib | 2 + 6 = 8 |
| 3rd Plhaub | 3 s, 3d, ib | 2 + 6 + 10 = 18 |
| 4th Plhaub | 4s, 4d, 4f | 2 + 6 + 10 + 14 = 32 |
