Txawm li cas los xij, lub tswv yim hais tias cov hluav taws xob tuaj yeem hloov mus ib puag ncig ntawm lub hauv paus loj nrog lub zog angular tseeb tau sib cav txog yam tsawg kawg 19 xyoo dhau los. Niels Bohr , thiab Japanese physicist Hantaro Nagaoka tau luam tawm ib qho kev xav raws li orbit rau kev coj cwj pwm hauv hluav taws xob thaum ntxov li xyoo 1904.
Tom qab ntawd, ib tug kuj yuav nug, thaum twg electron shells nrhiav tau?
Xyoo 1913 Bohr tau tshaj tawm nws qhov quantized plhaub qauv ntawm lub atom piav qhia li cas electrons tuaj yeem muaj qhov chaw ruaj khov nyob ib ncig ntawm lub nucleus.
Ib sab saum toj, dab tsi yog electron orbits hu ua? Txhua orbital muaj npe. Cov orbital nyob los ntawm hydrogen hluav taws xob yog hu ua ib a1s orbital . Qhov "1" sawv cev rau qhov tseeb tias tus orbital yog nyob rau hauv lub zog theem ze tshaj rau lub nucleus. Tus "s" qhia koj txog cov duab ntawm tus orbital.
Muaj pes tsawg electrons nyob rau hauv thawj lub orbital?
ob tug electrons
Leej twg ua pov thawj Rutherford yuam kev?
Xyoo 1912 Bohr koom nrog Rutherford . Nws paub qhov ntawd Rutherford tus qauv tsis zoo. Los ntawm tag nrho cov kev cai ntawm classical physics, nws yuav tsum tsis ruaj tsis khov. Rau ib yam, lub orbiting electrons yuav tsum muab tawm lub zog thiab nws thiaj li muab kauv mus rau hauv lub nucleus, ua rau lub atom vau.

Leej twg nrhiav tau tus qauv ntawm DNA quizlet?
Cov kws tshawb fawb tau lees paub (Tshaj tawm xyoo 1953 hauv 'Nature') nrog kev tshawb pom ntawm cov qauv ntawm DNA. Txawm hais tias Watson thiab Crick tau txais txiaj ntsig nrog qhov kev tshawb pom, lawv yuav tsis paub txog cov qauv yog lawv tsis pom kev tshawb fawb los ntawm Rosalind Franklin thiab Maurice Wilkins
Archimedes yog leej twg thiab nws nrhiav tau dab tsi?
Archimedes, (yug c. 287 bce, Syracuse, Sicily [Italy]-tuag 212/211 bce, Syracuse), tus kws ua lej nto moo tshaj plaws thiab tus tsim khoom hauv tebchaws Greece thaum ub. Archimedes yog qhov tseem ceeb tshwj xeeb rau nws qhov kev tshawb pom ntawm kev sib raug zoo ntawm qhov chaw thiab ntim ntawm ib puag ncig thiab nws lub tog raj kheej ncig
Leej twg nrhiav tau lub ntiaj teb magnetic teb?
Tsis tas li ntawd nyob rau hauv lub xyoo pua no, Georg Hartmann thiab Robert Norman nws tus kheej nrhiav tau magnetic inclination, lub kaum sab xis ntawm magnetic teb thiab kab rov tav. Tom qab ntawd xyoo 1600 William Gilbert luam tawm De Magnete, uas nws xaus lus tias lub ntiaj teb coj tus cwj pwm loj heev
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
Leej twg yog leej niam leej txiv pab txhawb cytoplasmic qub txeeg qub teg?
Nyob rau hauv cov ntaub ntawv ntawm cytoplasmic qub txeeg qub tes, cov teebmeem ntawm niam txiv. Qhov no feem ntau yog vim muaj kev koom tes ntau dua ntawm cytoplasm rau zygote los ntawm niam txiv poj niam dua li txiv neej niam txiv. Feem ntau ovum txhawb ntau cytoplasm rau zygote dua cov phev
