Hauv isotopic sau ntawv , tus naj npawb ntawm cov isotope yog sau raws li ib tug superscript nyob rau hauv pem hauv ntej ntawm cov tshuaj cim rau qhov ntawd. Hauv hyphen notation , tus lej loj yog sau tom qab lub npe ntawm lub caij. Hauv hyphen notation , nws yuav raug sau ua carbon-12.
Yog li ntawd, ua li cas koj sau lub cim nuclear thiab hyphen notation?
Nuclear Notation Nco tseg: hauv hyphen notation , tus lej tom qab hyphen yog tus lej loj (protons + neutrons). Rau Lub Sij Hawm Lub Sij Hawm, Tus lej Atomic nyob rau sab saum toj thiab qhov nruab nrab atomic loj nyob hauv qab. Rau Nuclear daim ntawv , tus lej ntawm cov isotope mus rau sab saum toj thiab tus lej atomic mus rau hauv qab.
Qhov thib ob, dab tsi yog hyphen notation rau nitrogen? tus lej atomic = tus naj npawb ntawm protons = tus naj npawb ntawm electrons huab hwm coj = tus naj npawb ntawm protons + tus naj npawb ntawm neutrons tus lej atomic = 7 (nitrogen) huab hwm coj = 7 protons + 9 neutrons = 16 nuclide yog nitrogen-16 009 10.0 ntsiab lus Uas tsis muaj tseeb rau isotopes ntawm ib lub caij? 1. Carbon-12 thiab carbon-14 yog cov isotopes.
Tsis tas li ntawd, lub cim nuclear yog dab tsi?
Lub cim nuclear muaj peb ntu: lub cim ntawm lub caij, lub tus lej atomic ntawm lub caij thiab tus lej loj ntawm cov isotope tshwj xeeb. Ntawm no yog ib qho piv txwv ntawm lub cim nuclear: Lub cim cim, Li, yog lithium.
Dab tsi yog lub cim nuclear rau silicon?
Silicon muaj atomic cim Si, atomic tooj 14, thiab atomic hnyav [28.084; 28.086] Nws.

Dab tsi yog hyphen notation?
Hauv hyphen notation, tus lej loj yog sau tom qab lub npe ntawm lub caij. Piv txwv li, hauv isotopic notation, lub isotope ntawm carbon uas muaj ib tug loj tus naj npawb ntawm kaum ob yuav sawv cev li 12C. Nyob rau hauv hyphen notation, nws yuav muab sau ua carbon-12
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog qhov kev sib txuas ua haujlwm ntawm nucleolus nuclear pores thiab nuclear membrane?
Dab tsi yog qhov kev sib txuas ua haujlwm ntawm nucleolus, nuclear pores, thiab daim nyias nyias? A. Lub nucleolus muaj tus xa xov RNA (mRNA), uas hla lub hnab ntawv nuclear los ntawm lub qhov pores nuclear
Dab tsi yog lub cim atomic rau ib lub atom nrog 82 protons thiab 125 neutrons?
Kev piav qhia: Lub isotope ntawm lub ntsiab X yog muab los ntawm AZX, qhov twg Z yog tus naj npawb proton ntawm lub caij thiab A yog tus lej ntawm lub caij. Tus lej ntawm cov isotope no yuav yog 82 + 125 = 207 units, thaum nws muaj 82 protons. Saib ntawm lub rooj zaum, lub ntsiab lus 82 yog txhuas, thiab nws lub cim yog Pb
Dab tsi yog asymptotic notation piav qhia qhov loj 0 cim?
Loj-O. Loj-O, feem ntau sau ua O, yog Asymptotic Notation rau qhov phem tshaj plaws, lossis lub qab nthab ntawm kev loj hlob rau ib qho kev ua haujlwm. Nws muab rau peb nrog asymptotic sab sauv khi rau kev loj hlob tus nqi ntawm lub sijhawm khiav ntawm ib qho algorithm
