Dear Tone,<br> Thank you very much for your reply. I want to know the flow from where to where?. Is it from lower electro negativity element to higher electro negativity element. How can we conform the type of bonding between them from these plots?.<br>

</div></div>It depends how you produced the charge density difference.<br>
<br>
Say, that you calculate the difference as:<br>
<br>
\Delta\rho = \rho(A-B) - \rho(A) - \rho(B),<br>
<br>
where \rho stands for electron density, A-B is the whole system, while A<br>
and B are the two fragments that constitute the A-B. In this case the<br>
positive values mean electron excess and negative values mean electron<br>
deficit.<br>
<br>
