Capture of a neutron by iron-58 produces what new element or isotope ?
Iron-59, because iron-59 has one more neutron than it's parent isotope. Déjà vu! I just answered a question exactly like this! --Yamakiri
No, does not produce cobalt, that would be the capture of a proton. Addition of a neutron would give you an isotope of iron 58.iron 59
