why is electronic charge in HCL is less than one, here quantisation of charge fails why? any one can answer it is a challange

Expert Answer

Electrons move very rapidly, as such they are smeared out in space. The two shared electrons in the bond move rapidly throughout the region of space spanning both the atoms. The uneven sharing of electrons in HCl is based on an average of where the electrons spend their time. This does not violate charge quantization. This means that the electron spends a certain fraction of time 'over there', and some other fraction of time 'over here'.

Here is an everyday example that might help you to understand how it works. Children are quantized - You can only have whole numbers of children, not fractions. But it would still be legitimate to say that the average family in a certain district has 2.35 children. You will never find an actual family with 2.35 children, just as you will never find an actual chlorine atom with an extra 0.1 of an electron!
