Cov electron tuaj yeem nce qhov zog nws xav tau los ntawm absorbing lub teeb. Yog hais tias lub electron dhia los ntawm qhov thib ob qib zog nqes mus thawj qib zog , nws yuav tsum muab tawm ib co zog los ntawm emitting lub teeb. Cov atom absorbs los yog emits lub teeb nyob rau hauv discrete pob ntawv hu ua photons, thiab txhua photon muaj ib tug meej zog.
Hais txog qhov no, vim li cas atoms muaj qib zog?
Qib zog hauv ib atom yog qhov tshwj xeeb lub zog uas electrons tuaj yeem muaj thaum tuav cov orbitals tshwj xeeb. Hluav taws xob ua tau zoo siab rau siab dua qib zog los ntawm absorbing zog los ntawm ib puag ncig. Teeb yog emitted thaum lub electron so los ntawm qhov siab zog xeev mus rau qis dua.
Tom qab ntawd, lo lus nug yog, vim li cas cov electrons nyob hauv qib zog? Niels Bohr hais tias electrons nyob rau hauv ib qho atom tau txwv rau cov orbits tshwj xeeb thiab muaj ib thaj tsam nyob ib ncig ntawm lub atom lub nucleus. Bohr sib cav tias ib hluav taws xob nyob rau hauv ib tug muab orbit muaj ib tug tas mus li zog , yog li ntawd nws thiaj tis npe rau tej chaw no qib zog . Yog li ntawd, peb hais tias lub zog ntawm lub electrons yog quantized.
Ua raws li qhov no hauv kev txiav txim siab, vim li cas atoms muaj qhov sib txawv ntawm lub zog?
Mus dhia los ntawm ib tug qib zog mus rau siab dua qib zog lub electron muaj kom nqus lub teeb, lub ntsiab lus zog , nws muaj nqus ib photon. Nws tsis tuaj yeem nqus ib feem ntawm photon, yog li nws tsis tuaj yeem muaj ib-nruab nrab qib , cov qib yog tsis paub meej , txhais tau tias yuav tsis muaj nyob rau hauv-nruab nrab qib.
Muaj pes tsawg lub zog nyob hauv atoms?
Tus naj npawb ntawm lub zog nyob rau hauv txhua lub sij hawm Lub atoms nyob rau hauv thawj lub sij hawm muaj electrons nyob rau hauv 1 qib zog. Lub atoms nyob rau hauv lub sij hawm thib ob muaj electrons nyob rau hauv 2 qib zog . Lub atoms nyob rau hauv peb lub sij hawm muaj electrons nyob rau hauv 3 qib zog. Lub atoms nyob rau hauv plaub lub sij hawm muaj electrons nyob rau hauv 4 qib zog.

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
Nyob rau hauv cov xwm txheej twg muaj zog elastic zog tam sim no?
Elastic muaj peev xwm muaj peev xwm muab khaws cia rau hauv cov roj hmab bands, bungee chords, trampolines, springs, ib tug xub kos rau hauv ib tug hneev nti, thiab lwm yam. Tus nqi ntawm elastic zog muaj peev xwm khaws cia nyob rau hauv xws li ib tug ntaus ntawv muaj feem xyuam rau tus nqi ntawm stretch ntawm lub ntaus ntawv - qhov ntau. stretch, lub zog khaws cia ntau dua
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Muaj pes tsawg electrons nyob hauv qib zog?
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 txog li ob lub tshuab hluav taws xob, lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav tau txog 18 (2 + 6 + 10). ) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons
Puas muaj peev xwm hluav taws xob thiab lub zog muaj peev xwm tib yam Vim li cas lossis vim li cas ho tsis?
Lub zog muaj peev xwm hluav taws xob Ue yog lub zog muaj peev xwm khaws cia thaum cov nqi tawm ntawm qhov sib npaug (xws li lub zog muaj peev xwm gravitational). Lub peev xwm hluav taws xob zoo ib yam, tab sis ib tus nqi, Ueq. Ib qho hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus hu ua voltage, V = Ue2q−Ue1q
