Which examples correctly identify an unstable nuclide and the reason why it is unstable? Select two that apply. 1.Uranium-238 (238U) is unstable because it has too few electrons and cannot provide enough strong nuclear force to hold the nucleus together. 2.Carbon-14 (14C) is unstable because it is small and falls right within the band of stability. 3.Carbon-14 (14C) is unstable because it falls outside the band of stability. 4.Uranium-238 (238U) is unstable because it is so large that the neutrons cannot provide enough strong nuclear force to hold the nucleus together.
