Ratio of the number of atoms in the n = 2 energy level

  1. Aug 9, 2010 #1
    1. The problem statement, all variables and given/known data

    a) Consider a sample of hydrogen atoms at a temperature of 300 K.

    i) What is the ratio of the number of atoms in the n = 2 energy level to those in the n = 1 level?

    ii) At what temperature would the ratio be 1/10?


    b) Assume that the conduction electrons in a piece of silver behave as a fermion gas, with each atom contributing one electron. Calculate the Fermi energy and compare this to the energy that would be expected classically at room temperature. Comment on your results.

    3. The attempt at a solution

    Please help me with setting up this problem no idea where to start

    Look up the Boltzmann equation and be careful about degeneracies.
