60, 6183 (2009). But you have to also consider that the adjacent atoms contain very little amount of charge; which will not help make the potential go very high. Chem. C 119, 1656016567 (2015). 114, 26152626 (2016). Phys. But if that is so, when atoms are so close to each other, even if there is barely any charge right beside the point, the potential will be turn out to be extremely high.
