Ngokwalokhu okushiwo ngenhla, yiziphi izakhi ezinzima kakhulu eziqhekeka kalula?
Context:Ukuhlanganiswa kwe-nuclear kuyisimo lapho ama-nucleus amabili noma ngaphezulu e-athomu ehlanganiswa khona ukuze kwakheke i-nucleus eyodwa noma ngaphezulu e-athomu nezinhlayiya ezingaphansi kwe-athomu (ama-neutron noma ama-proton). Umehluko ngobuningi phakathi kwama - reactants nemikhiqizo ubonakala njengokukhipha noma ukumuncwa kwamandla. Lo mehluko ngobuningi ubangelwa umehluko wamandla okubopha enuzi phakathi kwama-nucleus e-athomu ngaphambi nangemva kokusabela. Ukuhlanganiswa kwe-nuclear yinqubo enika amandla izinkanyezi ezisebenzayo noma ezilandelanayo nezinye izinkanyezi ezinamandla amakhulu, lapho kukhishwa khona amandla amaningi.  Inqubo yokuhlanganiswa kwe - nuclear ekhiqiza ama - nucleus e - athomu alula kunensimbi engu - 56 noma i - nickel - 62 ngokuvamile iyokhipha amandla. Lezi zakhi zinesisindo esincane kakhulu namandla amakhulu okubopha nge-nucleon ngayinye. Ukuhlanganiswa kwama-nucleus alula kunalokhu kukhipha amandla (inqubo ye-exothermic), kuyilapho ukuhlanganiswa kwama-nucleus asindayo kuphumela emandleni agcinwe yi-nucleons yomkhiqizo, futhi ukusabela okuvelayo kuyi-endothermic. Okuphambene kuyiqiniso ngenqubo ephambene, ebizwa ngokuthi ukuhlakazeka kwe-nuclear. Ukuhlanganiswa kwenuzi kusebenzisa izakhi ezikhanyayo, njenge-hydrogen ne-helium, ngokuvamile ezishintshashintshayo; kuyilapho izakhi ezisindayo, njenge-uranium, i-thorium ne-plutonium, zihlukaniseka kalula. Isenzakalo sezinkanyezi nezemvelo esibi kakhulu se-supernova singakhiqiza amandla anele okuxuba izinhlayiya zibe izinto ezisindayo kunensimbi.
i-uranium, i-thorium ne-plutonium.
