Density of Elements Chart
| Qhov ntom | Lub npe | Cim |
|---|---|---|
| 0,862 g/m² | Potassium | K |
| 0.971 g / cc | Sodium | Na |
| 1.55 g / c | Calcium | Ca |
| 1.63 g / ct | Rubidium | Rb |
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov ceev ntawm cesium?
Qhov ntom ntawm Cesium [Cs] Cesium hnyav 1.93 gram ib cubic centimeter los yog 1 930 kg ib cubic meter, i.e. density ntawm cesium yog sib npaug rau 1930 kg/m³; ntawm 20 ° C (68 ° F lossis 293.15K) ntawm tus qauv atmospheric siab.
Ib yam li ntawd, tus nqi ntawm rubidium yog dab tsi? Rubidium , zoo li sodium thiab potassium, yuav luag ib txwm muaj +1 oxidation lub xeev thaum yaj hauv dej, txawm nyob rau hauv cov ntsiab lus lom neeg. Tib neeg lub cev nyhav kho Rb + ions zoo li lawv yog potassium ions, thiab yog li ntawd concentrates rubidium nyob rau hauv lub cev cov kua dej intracellular (piv txwv li, hauv cov hlwb).
Ib yam li ntawd, koj tuaj yeem nug, rubidium rho tawm li cas?
Nyob rau hauv cov txheej txheem kev lag luam tseem ceeb ntawm rubidium ntau lawm, me me ntawm rubidium yog tau los ntawm kev sib tov ntawm alkali hlau carbonates tshuav tom qab lithium ntsev yog rho tawm los ntawm lepidolite. Rubidium peroxides ( Rb 2O2) tuaj yeem tsim los ntawm oxidation ntawm cov hlau nrog qhov xav tau ntawm cov pa oxygen.
Dab tsi yog qhov ceev ntawm francium?

Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua

Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
