Question

Determine the dipole moment of the system “electron – nucleus” of a hydrogen atom considering this atom as a dipole. Distance between the electron and the nucleus is l=10^-8 cm.

Answer 1

The dipole moment of this system is the value of the positive charge times distance between two the charges:

$$p=ql=1.602\cdot10^{-19}\cdot10^{-8}=1.602\cdot10^{-27}\text{ C}\cdot\text{m}.$$
