The problem’s specification is not clear.

Is it:

    homework(ListOfAtoms, TargetAtom, ReplacementAtom, ResultList)

where the ResultList is a copy of the ListOfAtoms with every instance of the TargetAtom replaced by ReplacementAtom? This would be a suitable problem for Prolog beginners.

Or is every *part* of of an atom which matches TargetAtom replaced (e.g., this_atom matches is_a)?  If so, there are then further specification issues involving multiple matching parts and rescanning after a change.

Tip:  Precise specifications are really really important, really.  Note that every syntactically correct program, no matter how awful, is the fully correct implementation of *some* specification.  (Reread that a few times until you understand it and believe it.)
