A nuclide 1 is said to be the mirror isobar of nuclide 2 if Z1 =N2 and Z2 =N1.
(a) What nuclide is a mirror isobar of Na1123"> ?
(b) Which nuclide out of the two mirror isobars have greater binding energy and why?
(a) From the question, we know that a nuclide 1 is to be the mirror isobar of nuclide 2
Z1 = N2 and Z2 = N1
Therefore, mirror isobar is Z2 = 12 – N1 and N2 = 23 -12 = 11 = Z1
(b) Mg has greater binding energy than Na.
