Txhua lub plhaub muaj peev xwm tsuas muaj tus naj npawb ruaj khov ntawm cov hluav taws xob: Thawj lub plhaub tuaj yeem tuav tau ob tug electrons , lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav txog 18 (2 + 6 + 10) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons.
Tsis tas li ntawd, muaj pes tsawg tus electrons nyob hauv qib 4 lub zog?
32 electrons
Muaj pes tsawg electrons nyob rau hauv qib 5 lub zog? 2 electrons
Tsis tas li ntawd, electrons pom nyob rau hauv cov qib zog li cas?
Cov ntsiab lus. Qib zog (tseem hu ua hluav taws xob shells) yog tsau nyob deb ntawm lub nucleus ntawm lub atom qhov twg electrons tej zaum pom . Thaum koj mus deb ntawm lub nucleus, electrons ntawm siab dua qib zog muaj ntau zog . Qhov siab tshaj plaws ntawm electrons ntawm ib qho muab qib zog nyob ntawm nws tus naj npawb ntawm orbitals.
Vim li cas thiaj tsis muaj electrons nyob nruab nrab ntawm lub zog?
Thaum ib hluav taws xob raug ntaus los ntawm hluav taws xob, nws tuaj yeem nce zog thiab tuaj yeem tsoo mus rau qhov siab dua zog orbit deb ntawm lub nucleus. Ntawm qhov tod tes, thaum ib hluav taws xob poob zog , nws poob rov qab mus rau qis dua zog orbit ze rau lub nucleus. Cov hluav taws xob yeej tsis tau muaj ntawm qhov deb hauv nruab nrab tso cai orbits.

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 zog muaj nyob hauv hydrogen?
Cov qauv qhia txog lub zog ntawm Hydrogen atom yog muab los ntawm qhov sib npaug: E = -E0 / n2, qhov twg E0 = 13.6 eV (1 eV = 1.602 × 10-19 Joules) thiab n = 1,2,3… ntawm
Muaj pes tsawg sublevels nyob rau hauv cov theem hauv qab no lub zog tseem ceeb?

Muaj pes tsawg valence electrons muaj nyob rau hauv lithium?
Lithium muaj 3 electrons --- 2 hauv thawj lub plhaub, thiab 1 hauv lub plhaub thib ob (yog li ib qho hluav taws xob valence)
Muaj pes tsawg electrons nyob rau hauv lub zog thib ob ntawm ib atom ntawm txhua lub caij?
Thaum thawj theem zog muaj 2 electrons, tom ntej no electrons mus rau theem ob lub zog mus txog rau theem thib ob muaj 8 electrons. Thaum lub zog thib ob muaj 8 electrons, tom ntej no electrons mus rau qib peb lub zog mus txog rau theem peb muaj 8 electrons
