Hauv hyphen notation , tus lej loj yog sau tom qab lub npe ntawm lub caij. Piv txwv li, hauv isotopic sau ntawv , cov isotope ntawm carbon uas muaj ib tug loj ntawm kaum ob yuav sawv cev li 12C. Hauv hyphen notation , nws yuav raug sau ua carbon-12.
Yog li ntawd, dab tsi yog hyphen notation rau nitrogen?
tus lej atomic = tus naj npawb ntawm protons = tus naj npawb ntawm electrons loj tus naj npawb = 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.
Ib tug kuj yuav nug, dab tsi yog qhov hyphen notation rau txhuas nrog lub cim nuclide?
| Lub npe | Aluminium |
|---|---|
| Cim | Al |
| Atomic Number | 13 |
| Atomic Mass | 26.982 atomic mass units |
| Tus naj npawb ntawm Protons | 13 |
Ib yam li ntawd, Nuclear notation yog dab tsi?
Nuclear Notation . Txuj Nuclear daim ntawv qhia cov cim tshuaj, tus lej loj thiab tus lej atomic ntawm isotope. Piv txwv li: cov isotopes ntawm carbon. Lub caij yog txiav txim los ntawm tus lej atomic 6. Carbon-12 yog cov isotope uas muaj, nrog carbon-13 yog lwm cov isotope ruaj khov uas ua rau li 1%.
Puas yog protons mus rau saum lossis hauv qab?
Muaj peb txoj hauv kev peb ua tau sawv cev rau lub ntsiab. Nco tseg: hauv hyphen notation, tus lej tom qab tus hyphen yog tus lej loj ( protons + neutrons). Rau Lub Sijhawm Teev Sijhawm, tus lej Atomic yog nyob rau saum thiab qhov nruab nrab atomic mass yog nyob rau hauv qab.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog lub cim nuclear thiab hyphen notation?
Nyob rau hauv isotopic notation, tus lej ntawm cov isotope yog sau raws li ib tug superscript nyob rau hauv pem hauv ntej ntawm cov tshuaj cim rau lub caij. Hauv hyphen notation, tus lej loj yog sau tom qab lub npe ntawm lub caij. Nyob rau hauv hyphen notation, nws yuav muab sau ua carbon-12
Dab tsi yog qhov orbital notation ntawm argon?
Lub p orbital muaj peev xwm tuav tau txog li rau rau electrons. Peb mam li muab rau hauv 2p orbital thiab tom qab ntawd muab ob lub electrons tom ntej hauv 3s. Txij li thaum 3s yog tam sim no tag nrho peb yuav txav mus rau 3p qhov twg peb yuav tso rau qhov seem rau electrons. Yog li ntawd, Argon electron configuration yuav yog 1s22s22p63s23p6
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
