You are in luck. I recently published a collection of references to many previous discussions on the behaviour and properties of various BIM element identifiers:

• Revit Element Id Compilation 
  https://thebuildingcoder.typepad.com/blog/2024/01/directcontext3d-ids-and-linked-section-elements-.h...

The ElementId is assigned per document. Afaik, it only changes if several copies of the same document exist, are edited independently, and need to be unified back into a single consistent state, e.g., by checking out, editing, and checking back in different worksets.

Other than that, the ElementId remains constant. Obviously, copying a model leaves the ids unchanged. For all further details, please refer to the compilation above.
