156. pm
and the average orbital speed of the electrons in it is about
×5.7*10^7 m/s.

Consider a gas at a temperature of 2 500 K whose atoms can occupy only two energy levels separated by 1.50 eV, where 1 eV (electron volt) is an energy unit equal to 1.60 × 10-19 J. Determine the ratio of the number of atoms in the higher energy level to the number in the lower energy level.

The atomic line spectra coming from elements such as hydrogen had been analyzed since the late 19th century. By studying the wavelength of the emerging radiation of hydrogen, experimenters found (often by trial and error) that the wavelengths in those spectra were described by the formula 1 = R ( 1/2 - 1/2 ) where R is known as the Rydberg constant. It has a value of R=1.097 × 107 m-¹. The variables n₁ and no are integer numbers (n₁ = 1, 2, 3, 4, ...). As experiments continued, scientists began to see more and more characteristic lines emerging from the hydrogen spectrum. Each of them corresponded to a wavelength predicted by this formula with some integer values for m₁ and ₂.
