Tus naj npawb ntawm orbitals hauv a plhaub yog lub square ntawm tus thawj quantum tooj: 12 = 1, 22 = 4, 32 = 9. Muaj ib orbital hauv s subshell (l = 0), peb orbitals hauv p subshell (l= 1), thiab tsib orbitals hauv d subshell (l = 2). Tus naj npawb ntawm orbitals hauv subshell yog li 2(l) +1.
Ib yam li ntawd, nws tau nug, muaj pes tsawg lub orbitals nyob hauv lub plhaub?
Qhov thib peb plhaub muaj 3 subshells: s subshell, uas muaj 1 orbital nrog 2 electrons, p subshell, uas muaj 3 orbitals nrog 6 electrons, thiab d subshell, uas muaj 5 orbitals nrog 10 electrons, rau tag nrho ntawm 9 orbitals thiab 18 electrons.
Tsis tas li ntawd, tag nrho cov orbitals hauv thawj Plhaub yog dab tsi? Txhua plhaub muaj peev xwm tsuas muaj ib tug ruaj tus lej ntawm electrons: The thawj lub plhaub tuaj yeem tuav tau txog li ob lub electrons, qhov thib ob plhaub tuaj yeem tuav txog yim (2 + 6) electrons, thib peb plhaub tuaj yeem tuav txog 18 (2 + 6 + 10) thiab lwm yam. Thegeneral formula yog qhov nth plhaub tuaj yeem nyob hauv txoj cai tuav txog 2(n2) electrons.
Tsis tas li ntawd, ua li cas koj pom cov naj npawb ntawm orbitals hauv lub plhaub?
Qhov tseem ceeb quantum tus lej ,n, txiav txim qhov qib zog ntawm electron nyob rau hauv ib atom . Muaj2 orbitals rau txhua tus qib zog . Yog li forn = 3 muaj cuaj orbitals , thiab rau n = 4 muaj 16 orbitals.
Muaj pes tsawg lub orbitals nyob hauv 7f?
Rau ib qho atom, muaj xya 7 forbital.

Muaj pes tsawg lub orbitals nyob hauv qib tsib lub zog tseem ceeb?
Thawj Quantum Number: Orbital thiab Electron xam muaj n2 orbitals rau txhua qib zog. Rau n = 1, muaj 12 lossis ib lub orbital. Rau n = 2, muaj 22 los yog plaub orbitals. Rau n = 3 muaj cuaj orbitals, rau n = 4 muaj 16 orbitals, rau n = 5 muaj 52 = 25 orbitals, thiab lwm yam
Muaj pes tsawg lub orbitals nyob rau hauv lub plhaub N 4?
L=3 rau f subshell. Tus naj npawb ntawm orbitals yog = 2l + 1 = 7. Nws tuaj yeem ua rau tag nrho 14 electron. Li no rau lub plhaub ntawm tus thawj quantum tooj n = 4 muaj 16 orbitals, 4 subshells, 32 electrons (siab tshaj) thiab 14 electrons nrog l = 3
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Muaj pes tsawg lub orbitals muaj nyob hauv M plhaub?
Lub plhaub M tsuas tuav yim electrons. Lub plhaub M tuaj yeem tuav txog 18 electrons thaum koj txav mus rau ntau dua atomic tooj. Qhov siab tshaj plaws ntawm cov hluav taws xob koj yuav pom hauv ib lub plhaub yog 32
Muaj pes tsawg lub orbitals nyob rau hauv lub plhaub nrog n 5?
Rau n = 3 muaj cuaj orbitals, rau n = 4 muaj 16 orbitals, rau n = 5 muaj 52 = 25 orbitals, thiab lwm yam
