Give an example for to say that “atomic sized particles exhibit wave nature” .

@ mardana 
as far as atomic size particles are concerned , in that case , they exhibits both wave nature and particle nature , the wave nature can be understand by the example of interference , diffraction etc , and the particle nature can be understand by the photoelectric effect and the compton effect . 
as nature loves symmatry , so, it can exhibits in dual form of nature , but not simoultaneously , . 
HOPE IT CLEARS
