1. The problem statement, all variables and given/known data
List out the evidences of quantisation of charge.


2. Relevant equations



3. The attempt at a solution
Like, what evidence is there for charge quantisation?

graphene

The charge on atomic nuclei is an integral multiple of a proton's charge.
The charge of an ion too is an integral multiple of an electron's charge.

AJ Bentley

And don't forget the quantisation of the magnetic field in a superconductor.
