# Exercise 3.2-3 Electronic Polarization

| Look at an atom with atomic number z.
|  | How large is the distance d between the (center of gravity) of the positive and negative charges for reasonable field strengths and atomic numbers, e.g. the combinations of 1 kV/cm 100 kV/cm 10 MV/cm , the last one being about the ultimate limit for the best dielectrics there are, and z = 1 (H, Hydrogen) z = 50 (Sn, (= tin), ...) z = 100 (?)
|  | Calculate the "spring constant" and from that the resonance frequency of the "elctron cloud" (assume the nucleus to be fixed in space).
| Link to the solution
