Ntev npaum li tus naj npawb ntawm protons hauv ib atom sib npaug tus naj npawb ntawm electrons, lub atom seem tsis tau them nqi , los yog nruab nrab. Thaum ib atom nce lossis poob electrons, nws dhau los ua hluav taws xob ion.
Tsis tas li ntawd, qhov twg ntawm cov kev sib raug zoo no muaj tseeb ntawm lub atom uas tsis muaj nqi?
Tus naj npawb ntawm protons yog sib npaug ntawm cov electrons. Dab tsi txiav txim siab hom tshuaj tiv thaiv uas ib atom koom nrog? Tus naj npawb ntawm cov electrons nyob rau sab nraud ntawm lub plhaub electron.
Ib sab saum toj, nqe lus twg muaj tseeb ntawm atoms? - Feem ntau ntawm ib atom cov ntim puv nrog cov teeb meem. - Protons tiv thaiv electrons. - Tag nrho cov saum toj no. Cov nqe lus uas yog TIAS txog atoms yog electrons txiav txim qhov loj ntawm lub atom ” Cov electrons ncig lub nucleus ntawm ib atom thiab lawv txiav txim qhov chaw nyob rau hauv uas ib tug atom nyob.
Tsuas yog li ntawd, dab tsi yog uncharged hais?
Neutron: Ib uncharged particle pom nyob rau hauv lub nucleus ntawm ib tug atom. Ib tug neutron, zoo li ib tug proton, pab txhawb ib atomic mass unit rau tag nrho cov atomic hnyav ntawm ib tug atom. Proton: Ib qho txiaj ntsig zoo particle pom nyob rau hauv lub nucleus ntawm ib tug atom. Qhov kev tawg no ua rau cov tawg me me ntawm cov atoms thiab lub zog.
Muaj pes tsawg tus electrons nyob hauv ib qho atom uas tsis tau them nqi ntawm lub caij 117?
Xeev: Uncharged atoms muaj tib tus lej ntawm electrons raws li protons. Yuav ua li cas ntau electrons muaj nyob rau hauv ib tug uncharged atom ntawm lub caij 117 ? Cov keeb carbon muaj atomic tus naj npawb ntawm 6 vim nws muaj 6 protons. Nws cov isotope feem ntau muaj cov lej ntawm 12 vim nws muaj 6 neutrons ntxiv rau 6 protons.

Dab tsi yog tus nqi ntawm lub atom uas tau txais electrons?
Ib qho ion yog ib qho atom uas tau txais lossis poob ib lossis ntau dua electrons thiab yog li ntawd muaj qhov tsis zoo lossis qhov zoo. Ib qho cation yog ib qho atom uas tau poob ib qho hluav taws xob valence thiab yog li ntawd muaj ntau qhov zoo protons dua li cov hluav taws xob tsis zoo, yog li nws raug nqi zoo
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
