Predict whether each of the following nuclides is stable or
unstable (radioactive). If the nuclide is unstable, predict the
type of radioactivity you would expect it to exhibit.
I have the answers but don't understand part of them.
(a) 20^11_Na
Stable (I understand why, the mass is too light to be
stable.)
But why are the types of radioactivity electron capture and
positron production? Why not alpha decay too? Those three are all
used when the nucleus is too light, so...
A nuclear scientist attemps to perform experiments on the stable
nuclide 56Fe26. Determine the energy (in MeV) the scientist will
need to: 1. remove a single neutron 2. remove a single proton 3.
completly dismantle the nucleus into its individual nucleons 4.
fission it simmetrically into two identical lighter nuclides
