Polonium
Tsis tas li ntawd, nyob qhov twg yog cov xov tooj cua tshaj plaws nyob rau hauv lub sijhawm?
Actinide Series ntawm Hlau Muaj ob kab hauv qab daim ntawv qhia hnub : lanthanide thiab actinide series. Lub lanthanide series tuaj yeem pom nyob rau hauv lub ntiaj teb. Tsuas yog ib qho xwb keeb hauv series yog xov tooj cua.
Kuj Paub, dab tsi yog tag nrho cov xov tooj cua nyob rau hauv lub sij hawm? Radioactive Elements
| Element | Feem ntau ruaj khov Isotope | Ib nrab-lub neej ntawm Feem ntau Stable Istope |
|---|---|---|
| Radon | Rn-222 | 3,82 noj |
| Francium | Ib-223 | 22 feeb |
| Radium | Rau-226 | 1600 xyoo |
| Actinium | Ac-227 | 21.77 y os |
Kuj tseem paub yog, dab tsi yog qhov txaus ntshai tshaj plaws xov tooj cua?
Plutonium
Dab tsi yog qhov txaus ntshai tshaj plaws thiab vim li cas?
Plutonium (Pu): Kev tshawb nrhiav lub vev xaib nrawm yuav qhia rau koj tias, zoo li, txhua tus xav plutonium yog super txaus ntshai. Yeej, peb cov phooj ywg Pu yog siv los ua cov foob pob atomic thiab tsim hluav taws xob nuclear. Tsis tas li ntawd, nws yog tshuaj lom heev vim nws cov xov tooj cua.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
