Thaum tus naj npawb ntawm cov protons txhais cov ntsiab lus (xws li hydrogen, carbon, thiab lwm yam) … ruaj khov isotopes tsis lwj mus rau lwm cov khoom . Nyob rau hauv sib piv, radioactive isotopes radioactive isotopes A radionuclide (radioactive nuclide, radioisotope los yog radioactive isotope) yog ib lub atom uas muaj ntau tshaj nuclear zog, ua rau nws tsis ruaj khov. … Cov xov tooj cua decay tuaj yeem tsim cov nuclide ruaj khov lossis qee zaum yuav tsim cov xov tooj cua tsis ruaj khov tshiab uas yuav raug puas tsuaj ntxiv. https://en.wikipedia.org › wiki › Radionuclide

(piv txwv li, 14C) tsis ruaj khov thiab yuav lwj mus rau lwm yam.
Dab tsi txiav txim siab qhov isotope ruaj khov?
Nuclear Stability yog lub tswvyim uas pab txheeb xyuas qhov ruaj khov ntawm isotope. Ob yam tseem ceeb uas txiav txim siab txog kev ruaj ntseg nuclear yog tus neutron / proton piv thiab tag nrho cov nucleons hauv nucleus.
Puas yog tag nrho cov isotopes ruaj khov Vim li cas lossis vim li cas ho tsis?
Qee lub ntsiab lus tsis muaj isotopes ruaj khov, uas txhais tau hais tias ib qho atom ntawm lub ntsiab lus yog xov tooj cua. … Carbon-12, nrog rau rau protons thiab rau neutrons, yog ib tug ruaj khov nucleus, txhais tau hais tias nws tsis spontaneously emit radioactivity. Carbon-14, nrog rau 6 protons thiab yim neutrons, tsis ruaj khov thiab ib txwm muaj hluav taws xob.
Puas isotopes ib txwm ruaj khov?
Tsuas 90 isotopes xav kom ruaj khov zoo kawg nkaus, thiab ntxiv 162 lub zog tsis ruaj khov, tab sis muajyeej tsis tau pom kom lwj. Yog li, 252 isotopes (nuclides) ruaj khov los ntawm txhais tau tias (xws li tantalum-180m, uas tseem tsis tau pom qhov lwj).
Dab tsi ua rau isotope tsis ruaj khov?
Feem ntau, dab tsi ua rau isotope tsis ruaj khov yog lub nucleus loj. Yog hais tias ib tug nucleus ua loj txaus los ntawm tus naj npawb ntawm neutrons, vim hais tias cov neutron suav yog dab tsi ua rau isotopes, nws yuav tsis ruaj khov thiab yuav sim 'tso' nws cov neutrons thiab / los yog protons thiaj li ua tiav stability.

Vim li cas emulsion tsis ruaj khov?
Emulsions yog cov tshuab thermodynamically tsis ruaj khov thiab nrawm nrawm rau hauv nyias txheej ntawm cov roj thiab dej [21]. Qhov no yog vim sib txawv ntawm cov roj thiab aqueous theem thiab kev sib cuag tsis zoo ntawm cov roj thiab dej molecules [
Puas khov kho thiab ruaj khov zoo ib yam?
Stable thiab khov kho ob leeg muaj ze rau tib yamlub ntsiab lus, txawm li cas los xij muaj qhov sib txawv me me. Stable txhais tau hais tias xijpeem koj tab tom tham txog nws nyob ntsiag to / zoo ib yam / tsis hloov lub sijhawm. Steady txhais tau hais tias nws nyob twj ywm / sib npaug / tsis hloov mus rau lub sijhawm txuas ntxiv.
Vim li cas huab cua nyob ruaj khov?
Cov huab cua tau hais kom ruaj khov yog tias ib puag ncig lapse tus nqi tsawg dua qhov moist adiabatic lapse rate. Qhov no txhais tau hais tias qhov nce ntawm huab cua parcel yuav ib txwm txias ntawm tus nqi nrawm dua li ib puag ncig, txawm tias tom qab nws ncav cuag saturation.
Puas muaj qhov chaw ruaj khov puas txhais tau tias tsis muaj zog nyob ruaj khov?
Thawj zaug nco ntsoov tias lub sijhawm kawg thib ob tsis suav tias yog lub ntsiab lus ntawm qhov muaj zog nyob ruaj khov, yog li, muaj zog ruaj khov tsis tas txhais tau tias tsis muaj zog nyob ruaj khov. Puas muaj zog nyob ruaj khov txhais tau tias tsis muaj zog nyob ruaj khov?
Puas muaj isotope ruaj khov?
khov isotopes tsis lwj mus rau lwm cov ntsiab lus . Nyob rau hauv sib piv, radioactive isotopes radioactive isotopes A radionuclide (radioactive nuclide, radioisotope los yog radioactive isotope) yog ib lub atom uas muaj ntau tshaj nuclear zog, ua rau nws tsis ruaj khov.
