Ib yam li ib tug yuav nug, puas yog daim ntawv teev sijhawm zoo ib yam hauv txhua hom lus?
Element npe in yam lus sib txawv tsis yog ib txwm muaj ib yam . Txawm hais tias International Union of Pure and Applied Chemistry (IUPAC) muaj tus qauv daim ntawv qhia hnub thiab daim ntawv teev cov tshuaj, cov npe thiab cov cim koj pom ntawm koj daim ntawv qhia hnub feem ntau nyob ntawm qhov twg lus koj hais thiab lub teb chaws koj nyob.
Tsis tas li ntawd, cov ntsiab lus twg muaj npe tom qab lub tebchaws? Qee lub ntsiab lus tshuaj muaj npe tom qab qhov chaw nyob hauv ntiaj chaw ntiaj teb. Tsib muaj npe tom qab lub tebchaws tam sim no - polonium (lub npe tom qab Poland), francium thiab gallium (npe tom qab Fabkis), nihonium (npe tom qab Nyiv) thiab germanium (lub npe tom qab lub teb chaws Yelemees).
Ntxiv mus, yog vim li cas lub sij hawm nyob rau hauv Latin?
Qhov tseeb, cov lus xaiv cov ntsiab lus hauv lub daim ntawv qhia hnub xws li hydrogen, oxygen, thiab phosphorus tsis yog Latin . Lawv yog Greek nyob rau hauv Latin txhais lus. Qhov tseeb, cov lus xaiv cov ntsiab lus hauv lub daim ntawv qhia hnub xws li hydrogen, oxygen, thiab phosphorus tsis yog Latin . Lawv yog Greek nyob rau hauv Latin txhais lus.

Lub ib hlis ntuj 24, 2016. Txhua square ntawm lub periodic rooj muab yam tsawg kawg nkaus lub npe ntawm lub caij, nws cov cim, atomic tooj thiab txheeb ze atomic mass (atomic hnyav)
Lub sij hawm ntawm lub sij hawm geology yog dab tsi?
Cov sij hawm no tsim cov ntsiab lus ntawm kev sib faib ntawm cov geologists tau faib lub ntiaj teb keeb kwm. Eons thiab eras yog cov subdivisions loj dua lub sij hawm thaum lub sij hawm lawv tus kheej yuav muab faib ua epochs thiab hnub nyoog. Cov pob zeb tsim nyob rau hauv ib lub sij hawm yog nyob rau hauv lub stratigraphic unit hu ua ib tug system
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
