<prompt> I-radius ye-nucleus icishe ilingane ne-1.07 3A fm, lapho i-A iyisibalo esiphelele se-nucleus. Lokhu kuncane kakhulu kunebanga le-athomu, elilinganiselwa ku-105 fm. Ama-nucleon ahlanganiswe ndawonye yi-short-range attractive potential ebizwa ngokuthi i-residual strong force. Emazingeni amancane kunama-2.5 fm le mandla inamandla kakhulu kunamandla kagesi okwenza ama-proton akhokhiswa kahle ukuba axoshe omunye nomunye. Ama-athomu e-element efanayo anenani elifanayo lama-proton, abizwa ngokuthi inombolo ye-athomu. Ngaphakathi kwe-element eyodwa, inani lama-neutron lingashintsha, linquma ukuthi i-element i-neutronotope. Inani eliphelele lama-neutron kanye nama-proton e-nucleus. I-nucleus inquma inani eliphelele lama-neutron. Lokhu kuncane kakhulu kunebanga le-radius ye-athomu, elilinganiselwe ku-105 fm. Ama-nucleus ah  <response>: ama-nucleon
