Potassium muaj ntau dua ntawm electrons tshaj Neon.
Tom qab ntawd, hydrogen puas muaj electrons ntau dua li uranium?
yog 9.
Ib yam li ntawd, hydrogen puas muaj protons ntau dua uranium? Rau hydrogen , atomic mass yog 1 vim muaj ib proton thiab tsis muaj neutron. Rau helium, nws yog 4: ob protons thiab ob lub neutron. Cov feem ntau nquag isotope ntawm uranium muaj 92 protons thiab 146 neutron. Nws atomic tooj yog 92 thiab nws atomic mass yog 238 (92 + 146).
Yog li ntawd, dab tsi yog tag nrho cov electrons nyob rau hauv ib tug atom ntawm poov tshuaj?
Yog li ntawd, rau koj cov lus nug, Lub Sij Hawm Lub Sij Hawm qhia peb tias poov tshuaj muaj ib Atomic Number ntawm 19, yog li muaj 19 protons thiab 19 electrons.
Mercury puas muaj protons lossis electrons ntau dua li cov tin?
Nrhiav cov cim Hg rau mercury thiab Sn rau tin . Tus lej atomic yog tus lej loj (ntawv loj) tus lej nyob ib sab ntawm lub cim ntawm daim ntawv, thiab nws yog sib npaug rau tus lej ntawm protons . Atom nruab nrab muaj tib tus naj npawb ntawm protons raws li electrons , yog tias koj paub cov protons , koj kuj paub cov electrons.

Vim li cas cov poov tshuaj ntau dua li sodium GCSE?
Yog li, nyob rau hauv poov tshuaj, lub sab nraud electron yog zoo dua shielded los ntawm lub zog txaus nyiam ntawm lub nucleus. Nws ua raws, yog li ntawd, cov hluav taws xob sab nraud no yooj yim dua ploj dua li nws nyob hauv sodium, yog li cov poov tshuaj tuaj yeem hloov mus rau hauv daim ntawv ionic ntau dua li sodium. Yog li ntawd, poov tshuaj yog ntau reactive tshaj sodium
Puas yog cov plaub hau daj lossis cov plaub hau xim av muaj ntau dua?
Cov plaub hau xim av yog qhov tseem ceeb tshaj cov plaub hau daj. Cov me nyuam uas muaj ib tug xim av-haired allele thiab ib tug blonde-haired allele yuav nthuav cov plaub hau xim av thiab. Tsuas yog cov uas muaj ob lub ntsej muag plaub hau daj yuav muaj cov plaub hau daj
Puas yog gal4 protein nyob rau hauv cov poov xab ua tau zoo lossis tsis zoo ntawm GAL noob?
Gal4 transcription yam yog ib tug zoo regulator ntawm noob qhia ntawm galactose-induced noob. Cov protein no sawv cev rau tsev neeg loj ntawm cov kab mob ntawm cov kab mob, Gal4 tsev neeg, uas suav nrog ntau dua 50 tus tswv cuab hauv cov poov xab Saccharomyces cerevisiae xws li. Oaf1, Pip2, Pdr1, Pdr3, Leu3
Puas muaj kev cuam tshuam ntau dua nrog cov catalyst lossis tsis muaj?
Reactions xav tau ib tug npaum li cas ntawm lub zog thiaj li yuav tshwm sim. Yog tias lawv tsis muaj, huag zoo, cov tshuaj tiv thaiv tej zaum tsis tuaj yeem tshwm sim. Ib qho catalyst txo qis lub zog xav tau kom qhov kev tshwm sim tuaj yeem tshwm sim tau yooj yim dua. Lub zog xav tau los ua kom muaj qhov tshwm sim yog hu ua lub zog ua kom muaj zog
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
