We’re being asked to identify the starting nuclide for the nuclear reaction. It’s said that technetium–97 (9743Tc) is produced by the absorption of hydrogen–2 (21H) and the emission of 2 neutrons (10n).


From this, we can say that 21H is a reactant while 9743Tc and 10n are products. The incomplete nuclear equation is:


_____ + 21 9743Tc + 2 10n


Recall that the nuclear equation must be balanced with the same total atomic mass and atomic number on both sides.
