All integer values of the principal quantum number n, even verylarge ones, are allowed in atoms. In practice, it is very hard toexcite orbits that correspond to large n values in an atom unlessthe atom is totally isolated. Estimate the largest value of n thatwould be possible if you could make a gas of atomic hydrogen ofdensity ? = 5.3 10-10 g/cm3. For practical purposes, we regard aninteratomic spacing of at least three times the diameter of thelarge-n atom as total isolation.
