Yog li, nyob rau hauv ib lo lus, hlau yog ruaj khov heev. Tab sis, dab tsi txog helium thiab lwm yam cov pa roj ? Lawv suav hais tias yog cov ntsiab lus ruaj khov tshaj plaws nyob rau hauv tag nrho lub sijhawm teem sijhawm.
Hauv qhov no, lub ntsiab lus twg yog qhov ruaj khov tshaj plaws?
cov pa roj
Ib yam li ntawd, cov hlau lead yog qhov ruaj khov tshaj plaws? Ib txhia xav txog coj ua tus ruaj khov feem ntau ntawm tag nrho vim nws siab atomic tooj. Coj muaj peb ruaj khov isotopes thiab ib qho tsis ruaj khov isotope. Thawj isotope, Pb-204, yog me ntsis xov tooj cua thiab suav tias yog thawj zaug, txhais tau hais tias nws laus dua lub ntiaj teb nws tus kheej. Qhov no yog qhov tsis ruaj khov.
Raws li txoj cai, vim li cas hlau yog qhov ruaj khov tshaj plaws?
Hlau muaj lub zog siab tshaj khi rau ib nucleon yog li ntawd ruaj khov nucleus. ? Yog peb saib cov nuclei loj (ntau dua hlau ), peb pom tias ntxiv mus rau sab xis (ntau dua nucleon tus lej) tsawg dua ruaj khov cov nuclei. ? Qhov no yog vim lub zog khi rau ib lub nucleon tau txais tsawg dua.
Puas yog kub yog qhov ruaj khov tshaj plaws?
Kub muaj cov siab tshaj electron affinity ntawm tej hlau, ntawm 222.8 kJ/mol, ua Au− a ruaj khov hom.
