Lub configuration ntawm lub plhaub sab nraud ntawm Arsenic yog 4s24p3 yog li nws lub plhaub sab nraud muaj 5 electrons , yog li ua 5 valence electrons . Dab tsi ntawm atomic daim ntawv cog lus tshwm sim thaum lub valence electrons yog qhia?
Ib yam li ntawd, pes tsawg valence electrons puas muaj arsenic?
5 valence electrons
Tsis tas li ntawd, pawg 5 muaj pes tsawg valence electrons? Pawg 5 atoms muaj 5 valence electrons. Pawg 6 atoms muaj 6 valence electrons. Pawg 7 atom muaj 7 valence electrons.
Dab tsi yog qhov tsuas yog hlau nrog 5 valence electrons?
Cov ntsiab lus ntawm pawg 15 (kem) VA ntawm lub rooj sib tham txhua lub sijhawm muaj cov khoom siv hluav taws xob ntawm s2p3, muab lawv tsib valence electrons. Cov ntsiab lus no suav nrog Nitrogen (N), phosphorus (P), Arsenic (As), Antimony (Sb) thiab Bismuth (Bi).
Lub plhaub valence ntawm arsenic yog dab tsi?
Arsenic muaj 5 valence electrons . Nws yog sab nraud plhaub (4s thiab 4p) muaj 5 electrons , cov no yog cov valence electrons.

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 protons neutrons thiab electrons puas muaj arsenic?
Daim duab ntawm lub nuclear muaj pes tsawg leeg thiab hluav taws xob configuration ntawm ib tug atom ntawm arsenic-75 (atomic tooj: 33), feem ntau isotope ntawm lub caij no. Lub nucleus muaj 33 protons (liab) thiab 42 neutrons (xiav). 33 electrons (ntsuab) khi rau lub nucleus, txuas ntxiv tuav cov khoom siv hluav taws xob (ntiv nplhaib)
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
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
Muaj pes tsawg valence electrons puas muaj cesium ion?
Ans: Cesium tsis yog nruab nrab, nws muaj 1 valence electron. Cesium tsis yog nruab nrab, vim hais tias nws tsis yog ib tug noble roj. Nyob rau hauv thiaj li yuav kom ib tug nruab nrab nws yuav tsum muaj 8 valence electrons, Cesium tsuas muaj 1
