Pojavili se novi izotopi kiseonika koji prkose uva\u017eenim nau\u010dnim o\u010dekivanjima za njihovo pona\u0161anje, posebno s obzirom na njihove jedinstvene karakteristike. Rije\u010d je o izotopima kiseonik-27, a posebno kiseonik-28, oba koji posjeduju neobi\u010dno visok broj neutrona u svome jezgru.<\/p>\n
Kiseonik-28 predstavlja posebno zanimljivu enigmu za nau\u010dnike. Dok bi konvencionalne nau\u010dne pretpostavke ukazivale na njegovu stabilnost, taj se izotop brzo raspada, dovode\u0107i u pitanje prevla\u0111uju\u0107e pretpostavke o “\u010darobnim” brojevima koji upravljaju atomskim jezgrima, prenosi<\/a> zimo.dnevnik.hr.<\/p>\n Jezgra \u010dine nukleoni, odnosno subatomske \u010destice koje obuhvataju protone i neutrone. Iako atomski broj elementa zavisi o njegovom broju protona, koli\u010dine neutrona mogu se razlikovati, daju\u0107i razli\u010dite izotope. Kiseonik s osam protona tako mo\u017ee pokazati razli\u010dite brojeve neutrona.<\/p>\n","protected":false},"excerpt":{"rendered":" Pojavili se novi izotopi kiseonika koji prkose uva\u017eenim nau\u010dnim o\u010dekivanjima za njihovo pona\u0161anje, posebno s obzirom na njihove jedinstvene karakteristike.
