Qhov sib txawv tseem ceeb ntawm tus lej atomic thiab atomicity yog tus lej atomic hais txog tus naj npawb ntawm protons hauv lub nucleus ntawm lub atom whereas atomicity yog hais txog tus naj npawb ntawm atoms uas tsim ib qho molecule.
Atomic tooj thiab atomicity yog ob nqe lus sib txawv uas piav txog ob qhov xwm txheej sib txawv. Atomic naj npawb yog tus naj npawb ntawm protons uas muaj nyob rau hauv lub nucleus ntawm ib lub atom, thaum atomicity yog tag nrho cov atoms nyob rau hauv ib molecule.
Atomic Number yog dab tsi?
Atomic tooj yog tus naj npawb ntawm protons uas muaj nyob rau hauv lub nucleus ntawm lub atom. Yog li ntawd, nws tseem hu ua tus lej proton. Tus lej atomic yog tshwj xeeb rau ib qho tshuaj lom neeg. Qhov no ua rau nws yooj yim los txheeb xyuas cov khoom siv tshuaj siv tus lej proton. Tus nqi no zoo ib yam rau tus lej nqi ntawm cov nucleus. Ntxiv mus, yog tias peb xav txog ib qho atom uas tsis tau them nqi, tus naj npawb ntawm electrons kuj zoo ib yam li tus lej atomic.
Tus lej ntawm ib lub atom zoo ib yam li cov lej ntawm cov protons thiab neutrons ntawm lub atom. Feem ntau, protons thiab neutrons muaj ze li qhov sib xws. Qhov loj tsis xws luag ntawm nucleon khi yog ib txwm me me thaum piv rau nucleon loj. Yog li ntawd, cov atomic loj ntawm ib qho atom tshwm sim li ntawm 1% ntawm tag nrho cov xov tooj uas tau hais nyob rau hauv unified atomic mass units.
Atomicity yog dab tsi?
Atomicity yog tag nrho cov atoms tam sim no nyob rau hauv ib lub molecule. Cov molecules tuaj yeem yog monoatomic, diatomic, triatomic, lossis polyatomic. Monoatomic molecules tsuas muaj ib qho atom raws li cov molecule. Cov no feem ntau yog cov roj roj uas muaj lawv cov khoom siv hluav taws xob ua tiav. Diatomic molecules muaj ob lub atoms ib molecule. Ib yam li ntawd, triatomic molecules muaj peb atoms ib molecule. Ntxiv mus, polyatomic molecules muaj ntau tshaj peb atoms ib molecule. Cov hauv qab no yog qee qhov piv txwv ntawm cov qauv molecule sib txawv.
Monoatomic: Nws, Ne, Ar, Kr, thiab lwm yam.
Diatomic: H2, N2, O2, F2, thiab Cl2.
Triatomic: O3
YPolyatomic: P4, S8
Qee lub sij hawm, atomicity yog siv tib lub ntsiab lus raws li valency. Peb tuaj yeem siv lo lus no txhawm rau xa mus rau qhov siab tshaj plaws ntawm cov khoom muaj txiaj ntsig uas tau pom zoo rau lub caij. Feem ntau, tag nrho cov hlau thiab lwm cov ntsiab lus, nrog rau cov pa roj carbon, muaj cov txheej txheem nyuaj, qhov twg cov atoms loj, tsis muaj qhov kawg ntawm kev sib koom ua ke. Yog li ntawd, peb feem ntau qhia lawv atomicity li 1.
Nyob rau hauv ib qho homonuclear molecule, lub atomicity yuav txiav txim tau raws li qhov piv ntawm molecular hnyav thiab atomic hnyav. E.g. molecular hnyav ntawm cov pa molecule yog kwv yees li 31.999. Qhov hnyav atomic ntawm ib qho oxygen molecule yog kwv yees li 15.999. Los ntawm kev faib 31.999 los ntawm 15.999, peb tau txais cov lus teb 2, uas txhais tau hais tias lub atomicity ntawm cov pa molecule yog 2.
Qhov txawv ntawm Atomic Number thiab Atomicity yog dab tsi?
Atomic tooj thiab atomicity yog ob lub ntsiab lus sib txawv uas piav txog ob qhov xwm txheej sib txawv. Qhov sib txawv tseem ceeb ntawm tus lej atomic thiab atomicity yog tus lej atomic hais txog tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm atom, whereas atomicity yog hais txog tus naj npawb ntawm atoms uas ua rau ib qho molecule.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm tus lej atomic thiab atomicity hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Atomic Number vs Atomicity
Atomic tooj thiab atomicity yog ob lub ntsiab lus sib txawv uas piav txog ob qhov xwm txheej sib txawv. Qhov sib txawv tseem ceeb ntawm tus lej atomic thiab atomicity yog tus lej atomic hais txog tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm atom whereas atomicity yog hais txog tus naj npawb ntawm atoms uas ua rau ib qho molecule.
