One of the most known phenomena in physics is the Hall effect. This is mainly due to its simplicity and to the wide range of its theoretical and practical applications. To complete the pedagogical utility of the Hall effect in physics teaching, I will apply it here to determine the Faraday constant as a fundamental physical number and the number of valence electrons as a characteristic of a metallic element. Both of these Hall effect applications are conceptually accessible to university science students. (Contains 1 figure.)
