Ahydrogen atom consists of a positively charged nucleus and a negatively charged electron. so, it is an electric dipole whose dipole moment is given by the product of the electron's charge and its distance from the nucleus. (a) calculate the expectation value of the dipole moment of a hydrogen atom in a stationary state vnlm in cartesian coordinates think about the physical implication of the result (b) for the state 211 calculate the expectation values of the squares of the cartesian components of the dipole moment, (d2), (d2), and (d2) you will need to express cartesian coordinates in terms of spherical polar ones, i. e r sin cos p and so on.
