Feem ntau ntawm hnyav ntsiab , los ntawm oxygen mus txog ntawm hlau, xav tias yuav tsim nyob rau hauv cov hnub qub uas muaj tsawg kawg yog kaum npaug ntau npaum li peb lub hnub.

Ib yam li ntawd, cov ntsiab lus hnyav tsim nyob qhov twg?

Thaum lub sij hawm supernova, lub hnub qub tso tawm ntau lub zog nrog rau cov neutrons, uas tso cai cov ntsiab lus hnyav dua tshaj hlau, xws li uranium thiab kub, yuav tsum tau ua. Nyob rau hauv lub supernova tawg, tag nrho cov no cov ntsiab lus raug ntiab tawm mus rau qhov chaw.

Qhov thib ob, cov khoom hnyav yog dab tsi? A hnyav element yog ib keeb nrog tus lej atomic ntau dua 92. Thawj hnyav element yog neptunium (Np), uas muaj tus lej atomic ntawm 93. Ib txhia hnyav ntsiab yog tsim nyob rau hauv reactors, thiab ib co yog tsim artificially nyob rau hauv cyclotron thwmsim.

Ib yam li ib tug yuav nug, dab tsi yog qhov hnyav tshaj plaws uas tuaj yeem tsim hauv lub hnub qub?
